It also happens after I re-install the system from a freshly downloaded ISO file. The system freezes at the moment, it starts the gnome display manager. I file the bug-report after a partial upgrade just before I will reboot the system. If needed I can reboot in recovery mode, since the gnome display manager is not started in that case. I tried the continue button without effect and also "apt upgrade" and "apt dist-upgrade" do have the same effect I run the VM from the Host-OpenZFS file system, so I can restore to before the update. Recently I use a Virtualbox snapshot to restore the system to before the update/upgrade. If you need log files, let me know.
