Updating Qubes OS

This page is about updating your system while staying on the same supported version of Qubes OS. If you're instead looking to upgrade from your current version of Qubes OS to a newer version, see the Upgrade Guides.

It is very important to keep your Qubes OS system up-to-date to ensure you have the latest security updates, as well as the latest non-security enhancements and bug fixes.

Fully updating your Qubes OS system means updating:

You can accomplish this using the Qubes Update tool. By default, the Qubes Update tool will appear as an icon in the Notification Area when updates are available, but you can also start the tool manually by selecting it in the Applications Menu under "System Tools." Even if no updates have been detected, you can use this tool to check for updates manually at any time by selecting "Enable updates for qubes without known available updates," then selecting all desired items from the list and clicking "Next."

As an alterntaive to the Qubes Update tool, advanced users can update each of the three types of VMs manually. Visit the pages linked above for details about updating each type.

The final step is to make sure that all of your VMs are running a supported operating system so that they're all receiving upstream security updates. For example, you might be using a Fedora TemplateVM. The Fedora Project is independent of the Qubes OS Project. They set their own schedule for when each Fedora release reaches end-of-life (EOL). You can always find out when an operating system reaches EOL from the upstream project that maintains it, but we also make EOL announcements and publish guides for official TemplateVM operating systems as a convenience to Qubes users. When this happens, you should make sure to follow the guide to upgrade to a supported version of that operating system (see the Fedora upgrade guides and the Debian upgrade guides). The one exception is dom0, which doesn't have to be upgraded.
