It may have been a Linux kernel update. If you can choose an earlier version from your boot menu, try that. To confirm, you can see the installation history in /var/log/dnf.log* files. To downgrade specific packages, see https://www.qubes-os.org/doc/software-update-dom0/#how-to-downgrade-a-specific-package. If booting the earlier version works for you, you might want to use that instead of trying to downgrade packages but look for a way to keep more than just 2 versions in your default list or could accidentally lose the working one on your next upgrade. I think I saw a way to do that somewhere on this list. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
