I think I have the same issue but I'm not sure. I have a Rasp IP 400 that I've been running Ubuntu 21.10 desktop (vanilla Gnome via the vanilla packages) on for about a month. I'm booting directly from a USB attached disk. This weekend I did updates as I do most days but this time the system will no longer boot. I'm not familiar with the boot process on Arm/PIs so have been unable to fix it. I needed the machine so I used a fresh install on a different disk and keeping to 21.04. Today, missing Gnome 40, I decided to upgrade using "do-release-upgrade -d". All looked fine until the restart, the machine fails to boot.
I'll try recovering the installs using the suggested method but it could be an issue with the latest kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1937924 Title: kernel upgrade via apt 5.11.0.1015-raspi kills the OS on Raspberry Pi4B To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1937924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
