Keep the System Up to Date

There are two methods of keeping a KDE Linux system up to date: graphical, and using command-line tools.

Graphical

Updates are done through the Discover software center app. Discover handles both system updates as well as updates for Flatpak-based apps and add-on content.

Discover will notify you when updates are available; just click the notification to launch Discover and see what’s available. On Discover’s Updates page, click “Update All” when you’re ready to update.

Updates to apps take effect the next time the updated apps are launched, while system updates take effect the next time the machine is restarted.

Command-line

Alternatively, you can update the system using command-line tools in a terminal.

Check for system updates using updatectl check, and install the latest one with updatectl update. Restart the system to apply the update.

If greater verbosity is needed, use run0 /usr/lib/systemd/systemd-sysupdate update instead.

Check for Flatpak updates and interactively decide to install them or not using flatpak update.

Faster updates

You can speed up system updates by beta-testing the experimental delta updates feature! To turn it on, run the command run0 systemctl enable --now kde-linux-sysupdated.socket in a terminal window, then restart the system. Thereafter, your system updates should be significantly faster, especially when performing updates daily.

If you find that updates are actually slower, please report it at https://invent.kde.org/kde-linux/kde-linux/-/issues/280.
