Had the same issue, which also caused xfce4 and lightdm to fail completely.
This was caused by moved apparmor config for bubblewrap: /etc/apparmor.d/bwrap-userns-restrict was a symlink to /usr/share/apparmor/extra-profiles/bwrap-userns-restrict. The upgrade left the symlink broken and created /etc/apparmor.d/bwrap-userns- restrict.dpkg-new. So to solve simply run: sudo mv /etc/apparmor.d/bwrap-userns-restrict.dpkg-new /etc/apparmor.d/bwrap-userns-restrict -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2150400 Title: background does not load, it is black To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glycin/+bug/2150400/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
