Linux NVIDIA updates can be problematic, including Linux kernel updates for NVIDIA. My experience with NVIDIA updates on Kubuntu 18.04, 20.04, and 22.04, initialized in Discover (package manager, software center) is that NVIDIA updates can break things, so that the system no longer boots correctly. Probably, such issues can be repaired, but I am not experienced to fix such errors. In cases NVIDIA updates break things, I simply restore a recent image. I learned not to be tempted, when Discover offers any NVIDIA updates, including Linux kernel updates for NVIDIA. In case of NVIDIA updates, I leave updates alone, non-NVIDIA kernel updates as well. Next day, or in a couple of days, those updates are installed automatically, and the obligatory reboot is fine, with no boot issues. If automatic updating does not run in about a day, and you get impatient, then you can force installation by manually running unattended-upgrade. Manually running unattended-upgrade to force installation of Linux updates for NVIDIA works nicely, the reboot is OK, with no issues. To manually run unattended-upgrade: sudo unattended-upgrade -v (-v stands for 'show verbose output') Sources: https://manpages.ubuntu.com/manpages/jammy/en/man8/unattended-upgrade.8.html https://www.linuxbabe.com/ubuntu/automatic-security-update-unattended-upgrades-ubuntu https://www.geekbits.io/how-to-setup-automatic-kernel-updates-on-linux/
