DNF is the The Fedora Project package manager that is able to query for information about packages, fetch packages from repositories, install and uninstall packages using automatic dependency resolution, and update an entire system to the latest available packages. DNF performs automatic dependency resolution on packages you are updating, installing or removing, and thus is able to automatically determine, fetch and install all available dependent packages. DNF can be configured with new, additional repositories, or package sources, and also provides many plug-ins which enhance and extend its capabilities. DNF is able to perform many of the same tasks that RPM can; additionally, many of the command line options are similar. DNF enables easy and simple package management on a single machine or on groups of them.
GPG-서명된 꾸러미로 보안 꾸러미 관리
DNF provides secure package management by enabling GPG (Gnu Privacy Guard; also known as GnuPG) signature verification on GPG-signed packages to be turned on for all package repositories (package sources), or for individual repositories. When signature verification is enabled, DNF will refuse to install any packages not GPG-signed with the correct key for that repository. This means that you can trust that the RPM packages you download and install on your system are from a trusted source, such as The Fedora Project, and were not modified during transfer. See Configuring DNF and DNF Repositories for details on enabling signature-checking with DNF, or Checking Package Signatures for information on working with and verifying GPG-signed RPM packages in general.
DNF also enables you to easily set up your own repositories of RPM packages for download and installation on other machines.
Learning DNF is a worthwhile investment because it is often the fastest way to perform system administration tasks, and it provides capabilities beyond those provided by the PackageKit graphical package management tools.
DNF와 슈퍼유저 권한
You must have superuser privileges in order to use the dnf command to install, update or remove packages on your system. All examples in this chapter assume that you have already obtained superuser privileges by using either the su or sudo command.
꾸러미 확인과 최신화 하기
The quickest way to check for updates is to attempt to install any available updates by using the dnf upgrade command as follows:
~]# dnf upgrade 마지막 메타자료 만료 점검은 2015년 5월 14일 목요일 23시 23분 51초 (1시간 24분 32초 이전)에 수행되었습니다. 의존성이 해결되었습니다. 처리가 필요하지 않습니다 완료되었습니다!
Note that dnf upgrade installs only those updates that can be installed. If a package cannot be updated, because of dependency problems for example, it is skipped.
The dnf check-update command can be used see which installed packages on your system have new versions available, however it does not mean that they can be successfully installed. This command is therefore mostly useful in scripts and for checking for updated packages that were not installed after running dnf upgrade.

DNF presents the update information and then prompts you as to whether you want it to perform the update; DNF runs interactively by default. If you already know which transactions DNF plans to perform, you can use the
-yoption to automatically answer yes to any questions DNF may ask (in which case it runs non-interactively). However, you should always examine which changes DNF plans to make to the system so that you can easily troubleshoot any problems that might arise.
If a transaction does go awry, you can view DNF’s transaction history by using the dnf history command as described in Working with Transaction History.
DNF로 커널 최신화와 설치하기
DNF always installs a new kernel in the same sense that RPM installs a new kernel when you use the command rpm -i kernel. Therefore, you do not need to worry about the distinction between installing and upgrading a kernel package when you use the dnf command: it will do the right thing, regardless of whether you are using the dnf upgrade or dnf install command.
When using RPM, on the other hand, it is important to use the rpm -i kernel command (which installs a new kernel) instead of rpm -u kernel (which replaces the current kernel). See Installing and Upgrading Packages for more information on installing and updating kernels with RPM.
To update all packages and their dependencies, enter dnf upgrade without any arguments:
구성파일 변경 보존하기
You will inevitably make changes to the configuration files installed by packages as you use your Fedora system. RPM, which DNF uses to perform changes to the system, provides a mechanism for ensuring their integrity. See Installing and Upgrading Packages for details on how to manage changes to configuration files across package upgrades.

dnf list and related commands provide information about packages, package groups, and repositories.
All of DNF’s list commands allow you to filter the results by appending one or more glob expressions as arguments. Glob expressions are normal strings of characters which contain one or more of the wildcard characters * (which expands to match any character multiple times) and ? (which expands to match any one character).
glob 표현식으로 결과 필터링
Be careful to escape the glob expressions when passing them as arguments to a dnf command, otherwise the Bash shell will interpret these expressions as pathname expansions, and potentially pass all files in the current directory that match the globs to DNF. To make sure the glob expressions are passed to DNF as intended, either:
DNF searches only package names when using glob expressions. To search for a version of a package, include a dash and part of the version number as follows:

Displaying Package Information
To display information about one or more packages, use a command as follows:
dnf info package_name…
For example, to display information about the abrt package, type:
~]# dnf info abrt Last metadata expiration check: 1:09:44 ago on Tue May 31 06:51:51 2016. Installed Packages Name : abrt Arch : x86_64 Epoch : 0 Version : 2.8.1 Release : 1.fc24 Size : 2.2 M Repo : @System From repo : updates-testing Summary : Automatic bug detection and reporting tool URL : https://abrt.readthedocs.org/ License : GPLv2+ Description : abrt is a tool to help users to detect defects in applications and : to create a bug report with all information needed by maintainer to fix it. : It uses plugin system to extend its functionality.
The dnf info package_name command is similar to the rpm -q --info package_name command, but provides as additional information the name of the DNF repository the RPM package was installed from (look for the
From repo: line in the output). The dnf info command shows only the newest available package if there is a newer version available than the one installed. The dnf repoquery command can show all installed and available packages.
To display information about all available packages, both installed and available from a repository, use a command as follows:
dnf repoquery package_name --info
For example, to display information about the abrt package, type:
~]# dnf repoquery abrt --info Last metadata expiration check: 1:01:44 ago on Tue May 31 06:51:51 2016. Name : abrt Version : 2.8.1 Release : 1.fc24 Architecture: x86_64 Size : 2318452 License : GPLv2+ Source RPM : abrt-2.8.1-1.fc24.src.rpm Build Date : 2016-05-25 08:54 Packager : Fedora Project URL : https://abrt.readthedocs.org/ Summary : Automatic bug detection and reporting tool Description : abrt is a tool to help users to detect defects in applications and to create a bug report with all information needed by maintainer to fix it. It uses plugin system to extend its functionality.
See the dnf repoquery usage statement for more options:

DNF allows you to install both a single package and multiple packages, as well as a package group of your choice.
To install a single package and all of its non-installed dependencies, enter a command in the following form:
dnf install package_name
You can also install multiple packages simultaneously by appending their names as arguments:
dnf install package_name package_name…
If you are installing packages on a multilib system, such as an AMD64 or Intel64 machine, you can specify the architecture of the package, as long as it is available in an enabled repository, by appending .arch to the package name. For example, to install the sqlite2 package for
~]# dnf install sqlite2.i586
You can use glob expressions to quickly install multiple similarly-named packages:
~]# dnf install audacious-plugins-\*
In addition to package names and glob expressions, you can also provide file names to dnf install. If you know the name of the binary you want to install, but not its package name, you can give dnf install the path name:
~]# dnf install /usr/sbin/named
dnf then searches through its package lists, finds the package which provides
/usr/sbin/named, if any, and prompts you as to whether you want to install it.
Finding which package owns a file
If you know you want to install the package that contains the
~]# dnf provides "*bin/named" Using metadata from Thu Apr 16 13:41:45 2015 (4:23:50 hours old) bind-32:9.10.2-1.fc22.x86_64 : The Berkeley Internet Name Domain (BIND) DNS (Domain Name System) server Repo : @System
dnf provides "*/file_name" will find all the packages that contain file_name.
A package group is similar to a package: it is not useful by itself, but installing one pulls a group of dependent packages that serve a common purpose. A package group has a name and a groupid (GID). The dnf group list -v command lists the names of all package groups, and, next to each of them, their groupid in parentheses. The groupid is always the term in the last pair of parentheses, such as
kde-desktop-environment in the following example:
~]# dnf -v group list kde\* cachedir: /var/cache/dnf/x86_64/22 Loaded plugins: builddep, config-manager, copr, playground, debuginfo-install, download, generate_completion_cache, kickstart, needs-restarting, noroot, protected_packages, Query, reposync, langpacks initialized Langpacks plugin DNF version: 0.6.5 repo: using cache for: fedora not found deltainfo for: Fedora 22 - x86_64 not found updateinfo for: Fedora 22 - x86_64 repo: using cache for: updates-testing repo: using cache for: updates not found updateinfo for: Fedora 22 - x86_64 - Updates Using metadata from Thu Apr 16 13:41:45 2015 (4:37:51 hours old) Available environment groups: KDE Plasma Workspaces (kde-desktop-environment)
You can install a package group by passing its full group name (without the groupid part) to group install:
dnf group install group_name
Multi-word names must be quoted.
You can also install by groupid:
You can even pass the groupid, or quoted name, to the install command if you prepend it with an @-symbol (which tells dnf that you want to perform a group install):
For example, the following are alternative but equivalent ways of installing the
KDE Plasma Workspaces group:
~]# dnf group install "KDE Plasma Workspaces" ~]# dnf group install kde-desktop-environment ~]# dnf install @kde-desktop-environment
Similarly to package installation, DNF allows you to uninstall (remove in RPM and DNF terminology) both individual packages and a package group.
To uninstall a particular package, as well as any packages that depend on it, run the following command as
dnf remove package_name…
As when you install multiple packages, you can remove several at once by adding more package names to the command. For example, to remove totem, rhythmbox, and sound-juicer, type the following at a shell prompt:
~]# dnf remove totem rhythmbox sound-juicer
Similar to install, remove can take these arguments:
Removing a package when other packages depend on it
DNF is not able to remove a package without also removing packages which depend on it. This type of operation can only be performed by RPM, is not advised, and can potentially leave your system in a non-functioning state or cause applications to misbehave and terminate unexpectedly. For further information, refer to Uninstalling Packages in the RPM chapter.
You can remove a package group using syntax congruent with the install syntax:
The following are alternative but equivalent ways of removing the
KDE Plasma Workspaces group:
~]# dnf group remove "KDE Plasma Workspaces" ~]# dnf group remove kde-desktop-environment ~]# dnf remove @kde-desktop-environment
Working with Transaction History
The dnf history command allows users to review information about a timeline of DNF transactions, the dates and times on when they occurred, the number of packages affected, whether transactions succeeded or were aborted, and if the RPM database was changed between transactions. Additionally, this command can be used to undo or redo certain transactions.
To display a list of all transactions, as
root, either run dnf history with no additional arguments, or enter the following command:
To display only transactions in a given range, use the command in the following form:
dnf history list start_id..end_id
You can also list only transactions regarding a particular package or packages. To do so, use the command with a package name or a glob expression:
dnf history list glob_expression…
For example, the list of first five transactions may look as follows:
~]# dnf history list 1..4 Using metadata from Thu Apr 16 13:41:45 2015 (5:47:31 hours old) ID | Login user | Date a | Action | Altere ------------------------------------------------------------------------------- 4 | root <root> | 2015-04-16 18:35 | Erase | 1 3 | root <root> | 2015-04-16 18:34 | Install | 1 2 | root <root> | 2015-04-16 17:53 | Install | 1 1 | System <unset> | 2015-04-16 14:14 | Install | 668 E
The dnf history list command produces tabular output with each row consisting of the following columns:
ID— an integer value that identifies a particular transaction.
Login user— the name of the user whose login session was used to initiate a transaction. This information is typically presented in the
Full Name <username>form, however sometimes the command used to perform the transaction is displayed. For transactions that were not issued by a user (such as an automatic system update),
System <unset>is used instead.
Date and time— the date and time when a transaction was issued.
Action(s)— a list of actions that were performed during a transaction as described in Possible values of the Action(s) field.
Altered— the number of packages that were affected by a transaction, possibly followed by additional information.
At least one package has been downgraded to an older version.
At least one package has been removed.
At least one new package has been installed.
At least one package has been marked as obsolete.
At least one package has been reinstalled.
At least one package has been updated to a newer version.
Apart from reviewing the transaction history, the dnf history command provides means to revert or repeat a selected transaction. To revert a transaction, type the following at a shell prompt as
To repeat a particular transaction, as
root, run the following command:
Both commands also accept the
last keyword to undo or repeat the latest transaction.
Note that both dnf history undo and dnf history redo commands merely revert or repeat the steps that were performed during a transaction, and will fail if the required packages are not available. For example, if the transaction installed a new package, the dnf history undo command will uninstall it and also attempt to downgrade all updated packages to their previous version, but the command will fail if the required packages are not available.
Configuring DNF and DNF Repositories
The configuration file for DNF and related utilities is located at
/etc/dnf/dnf.conf. This file contains one mandatory
[main] section, which allows you to set DNF options that have global effect, and may also contain one or more
[repository] sections, which allow you to set repository-specific options. However, it is recommended to define individual repositories in new or existing
.repo files in the
/etc/yum.repos.d/ directory. The values you define in individual
[repository] sections of the
/etc/dnf/dnf.conf file override values set in the
This section shows you how to:
set global DNF options by editing the
[main]section of the
set options for individual repositories by editing the
.repofiles in the
use DNF variables in
/etc/dnf/dnf.confand files in the
/etc/yum.repos.d/directory so that dynamic version and architecture values are handled correctly;
add, enable, and disable DNF repositories on the command line; and,
set up your own custom DNF repository.
Setting [main] Options
/etc/dnf/dnf.conf configuration file contains exactly one
[main] section, and while some of the key-value pairs in this section affect how dnf operates, others affect how DNF treats repositories.
You can add many additional options under the
[main] section heading in
/etc/dnf/dnf.conf configuration file can look like this:
[main] gpgcheck=1 installonly_limit=3 clean_requirements_on_remove=true
The following are the most commonly-used options in the
…where value is an integer between
10. Setting a higher
debuglevelvalue causes dnf to display more detailed debugging output.
debuglevel=0disables debugging output, and
debuglevel=2is the default.
This option allows you to exclude packages by keyword during installation and updates. Listing multiple packages for exclusion can be accomplished by quoting a space-delimited list of packages. Shell globs using wildcards (for example,
?) are allowed.
…where value is one of:
0— Disable GPG signature-checking on packages in all repositories, including local package installation.
1— Enable GPG signature-checking on all packages in all repositories, including local package installation.
gpgcheck=1is the default, and thus all packages' signatures are checked.
If this option is set in the
[main]section of the
/etc/dnf/dnf.conffile, it sets the GPG-checking rule for all repositories. However, you can also set
gpgcheck=valuefor individual repositories instead; you can enable GPG-checking on one repository while disabling it on another. Setting
gpgcheck=valuefor an individual repository in its corresponding
.repofile overrides the default if it is present in
For more information on GPG signature-checking, refer to Checking Package Signatures.
installonlypkgs=space separated list of packages
Here you can provide a space-separated list of packages which dnf can install, but will never update. See the dnf.conf(5) manual page for the list of packages which are install-only by default.
If you add the
/etc/dnf/dnf.conf, you should ensure that you list all of the packages that should be install-only, including any of those listed under the
installonlypkgssection of dnf.conf(5). In particular, kernel packages should always be listed in
installonlypkgs(as they are by default), and
installonly_limitshould always be set to a value greater than
2so that a backup kernel is always available in case the default one fails to boot.
…where value is an integer representing the maximum number of versions that can be installed simultaneously for any single package listed in the
The defaults for the
installonlypkgsdirective include several different kernel packages, so be aware that changing the value of
installonly_limitwill also affect the maximum number of installed versions of any single kernel package. The default value listed in
installonly_limit=3, and it is not recommended to decrease this value, particularly below
…where value is one of:
0— Do not retain the cache of headers and packages after a successful installation. This is the default.
1— Retain the cache after a successful installation.
For a complete list of available
[main] options, refer to the
[MAIN] OPTIONS section of the dnf.conf(5) manual page.
Setting [repository] Options
[repository] sections, where repository is a unique repository ID such as
my_personal_repo (spaces are not permitted), allow you to define individual DNF repositories.
The following is a bare-minimum example of the form a
[repository] section takes:
[repository] name=repository_name baseurl=repository_url
[repository] section must contain the following directives:
…where repository_name is a human-readable string describing the repository.
…where parameter is one of the following:
…where repository_url is a URL to a directory containing a
repodatadirectory of a repository, a metalink file, or a mirror list file.
If the repository is available over HTTP, use:
If the repository is available over FTP, use:
If the repository is local to the machine, use:
If a specific online repository requires basic HTTP authentication, you can specify your user name and password by prepending it to the URL as
username:password@link. For example, if a repository on http://www.example.com/repo/ requires a username of “user” and a password of “password”, then the
baseurllink could be specified as
Usually this URL is an HTTP link, such as:
Note that DNF always expands the
$basearchvariables in URLs. For more information about DNF variables, refer to Using DNF Variables.
To configure the default set of repositories, use the
enabled option as follows:
…where value is one of:
0— Do not include this repository as a package source when performing updates and installs.
1— Include this repository as a package source.
Turning repositories on and off can also be performed by passing either the
--set-disabled repo_nameoption to the dnf command, or through the
Add/Remove Softwarewindow of the PackageKit utility.
[repository] options exist. For a complete list, refer to the
[repository] OPTIONS section of the dnf.conf(5) manual page.
Using DNF Variables
Variables can be used only in the appropriate sections of the DNF configuration files, namely the
/etc/dnf/dnf.conf file and all
.repo files in the
/etc/yum.repos.d/ directory. Repository variables include:
Refers to the release version of operating system which DNF derives from information available in RPMDB.
Refers to the system’s CPU architecture. Valid values for
Refers to the base architecture of the system. For example, i686 and i586 machines both have a base architecture of
i386, and AMD64 and Intel64 machines have a base architecture of
