Could restore a working Kernel 6.5.0.21 with $ sudo apt update $ sudo apt upgrade
However, the system starts up directly without asking for the user login, which is really weird. There is also a security warning when updating: $ sudo apt update Hit:1 http://archive.ubuntu.com/ubuntu mantic InRelease Hit:2 http://archive.ubuntu.com/ubuntu mantic-updates InRelease Hit:3 http://archive.ubuntu.com/ubuntu mantic-backports InRelease Hit:4 http://security.ubuntu.com/ubuntu mantic-security InRelease Ign:5 http://linux.dropbox.com/ubuntu mantic InRelease Hit:6 http://linux.dropbox.com/ubuntu mantic Release Get:7 http://linux.dropbox.com/ubuntu mantic Release.gpg [488 B] Ign:7 http://linux.dropbox.com/ubuntu mantic Release.gpg Hit:8 https://dl.google.com/linux/chrome/deb stable InRelease Reading package lists...
