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.

Updating by using the Software application

Actualización manual usando ICU

Esta sección describe como descargar manualmente e instalar actualizaciones nuevas utilizando el gestor de paquetes DNF.

Procedimiento

  1. Modernizar el sistema:

    sudo dnf upgrade

    Confirm to download the available packages.

  2. 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

Establcer actualizacoines automáticas

Esta sección describe como utilizar la aplicación DNF Automatic para automáticamente:

  • Descargar e instalar cualquier actualización nueva

  • Solamente descargar las actualizaciones

  • Get notified about the updates

Procedimiento

  1. Install the dnf-automatic package:

    sudo dnf install dnf-automatic

  2. Edit the /etc/dnf/automatic.conf configuration file as needed. See the DNF Automatic documentation for details.

  3. 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.

  4. 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
