Mengapa penting untuk selalu memperbarui sistem Anda

Bagian ini secara singkat menjelaskan pentingnya melakukan pembaruan sistem secara teratur.

All software contains bugs. Often, these bugs can result in a vulnerability that can expose your system to malicious users. Packages that have not been updated are a common cause of computer intrusions. Install security patches promptly to end discovered vulnerabilities quickly, so attackers cannot exploit them.

Pembaruan manual menggunakan GUI

The following steps describe how to manually download and install new updates by using GUI.

Prosedur

  1. Hover the cursor over the upper-left corner of the screen and type "Software" and select the Software application to open it.

  2. Klik Pembaruan untuk melihat pembaruan yang tersedia.

  3. Klik Unduh untuk mengunduh pembaruan terbaru.

  4. After the updates are downloaded click the Restart & Update button. Your system will restart to perform the upgrade.

Pembaruan menggunakan aplikasi Software

Pembaruan manual menggunakan CLI

The following steps describe how to manually download and install new updates by using the DNF package manager.

Fedora recommends applying updates offline: packages are downloaded while the system is running normally, then applied during a reboot. This avoids conflicts caused by updating libraries or services that are actively in use.

Prosedur

  1. Download available updates:

    $ sudo dnf offline-upgrade download

    Konfirmasi untuk mengunduh paket yang tersedia.

  2. Reboot to apply the updates:

    $ sudo dnf offline-upgrade reboot

    The system reboots, applies the downloaded updates, then starts normally.

  3. Optionally, use the rpmconf command to merge any configuration file changes introduced by the package updates:

    $ sudo rpmconf -a

    To use the advanced merge option, set the MERGE environment variable to an editor capable of performing that function (e.g., export MERGE="vimdiff"). See the man page for details.

    If you install the rpmconf DNF plugin, rpmconf runs automatically at the end of each upgrade:

    $ sudo dnf install python3-dnf-plugin-rpmconf

Sumber Daya Tambahan

  • Halaman manual dnf(8)

  • The dnf-offline-upgrade(8) manual page

  • Halaman manual rpmconf(8)

Mengaktifkan pembaruan otomatis

The dnf-automatic package provides a systemd timer that can automatically download, install, or alert you about available updates. Whether the timer downloads only, installs, or just notifies the options in the /etc/dnf/automatic.conf configuration file.
