How to enable automatic updates
Por qué es importante conservar su sistema al día
Esta sección explica brevemente la importancia de actualizar su sistema en una base usual.
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. Implement a plan for installing security patches in a timely manner to quickly eliminate discovered vulnerabilities, so they cannot be exploited.

Actualización manual usando ICU
Esta sección describe como descargar manualmente e instalar actualizaciones nuevas utilizando el gestor de paquetes DNF.
Procedimiento
-
Modernizar el sistema:
sudo dnf upgrade
Confirm to download the available packages.
-
Ideally (but it is usually not required), use the
rpmconf
command to merge any config file changes you may have made with any new settings that might have been introduced by the package updates. You should do this before you reboot your system:sudo rpmconf -a
To use the advanced merge option, you will need to set the
MERGE
environment variable to an editor that is capable of performing that function (e.g.,export MERGE="vimdiff"
). See the man page for details.If you install the rpmconf DNF plugin,
rpmconf
will run automatically at the end of each upgrade. Install it using the command:sudo dnf install python3-dnf-plugin-rpmconf

configuration file as needed. See the DNF Automatic documentation for details. -
Enable and start the
systemd
timer:sudo systemctl enable --now timer
Replace
timer
with one of following ones depending on what action you want to do:-
dnf-automatic-install.timer
to download and install packages -
dnf-automatic-download.timer
to only download packages -
dnf-automatic-notifyonly.timer
to only get a notification using configured emitters in the/etc/dnf/automatic.conf
file.
Por ejemplo:
sudo systemctl enable --now dnf-automatic-install.timer Created symlink /etc/systemd/system/timers.target.wants/dnf-automatic-install.timer → /usr/lib/systemd/system/dnf-automatic-install.timer.
-

Ensure that the timer has been successfully enabled and started:
sudo systemctl status timer
Replace
timer
with the timer from the previous step, for example:sudo systemctl status dnf-automatic-install.timer ● dnf-automatic-install.timer - dnf-automatic-install timer Loaded: loaded (/usr/lib/systemd/system/dnf-automatic-install.timer; enabled; vendor preset: disabled) Active: active (waiting) since Fri 2021-01-29 14:50:22 +08; 1s ago Trigger: Sat 2021-01-30 06:05:57 +08; 15h left Triggers: ● dnf-automatic-install.service Jan 29 14:50:22 localhost.localdomain systemd[1]: Started dnf-automatic-install timer.
