As previously announced, extended security support for Qubes OS 4.1 has ended as of yesterday, 2024-07-31. Qubes 4.1 will no longer receive updates of any kind, including security updates. We strongly recommend that any remaining Qubes 4.1 users upgrade to Qubes 4.2 immediately.

If you’re already using Qubes 4.2, then you don’t have to do anything. This announcement doesn’t affect you.

If you’re still using Qubes 4.1, then you should upgrade to Qubes 4.2 immediately. There are two ways to do this:

  1. Perform a clean reinstallation using the latest stable Qubes OS 4.2.2 ISO.
  2. Perform an in-place upgrade to Qubes 4.2.

Both of these options are covered in further detail in the Qubes 4.1 to 4.2 upgrade guide. In either case, we strongly recommend making a full backup beforehand. If you need help, please consult our help and support page.
