Since Dependencies.txt shows you have the broken (41.3-1ubuntu1) gdm3 installed, we can probably assume this really is bug 1960226. Although it's the first case of someone hitting it via updates that I have heard of. Previously it seemed like you would only have a problem if you installed from this week's ISOs.
Please test gdm3 version 41.3-1ubuntu2 ** Package changed: gnome-shell (Ubuntu) => gdm3 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960336 Title: No login screen after recent update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1960336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
