** Description changed: + [SRU] 2.68.4: + https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/2098137 + + [ Impact ] (Snapd snap in Ubuntu Core only) + + When combination of snapd 2.68+ and snap-boostrap <2.68 recovery keys + cannot be requested or created. + + [ Test Plan ] + + Already provided with confirmation that re-test on edge containing the + fix works. Need to re-test using snapd 2.68.3 snap. + + NOTE: Not required to re-test for snapd deb release (2.68.5), this is a + snap only issue so it is covered by snapd 2.68.4 snap. + + ---original--- + Laptop: ThinkPad 13 gen 2 OS: Ubuntu 24.04.2 LTS (Noble Numbat) with FDE/TPM I think I had an update of my laptop running noble of the kernel snap that made most of the interfaces unavailable. Also, I had to enter my FDE recovery key at some point during reboot process before noticing the issue. In order to fix this, I wanted to fallback to previous kernel through GRUB entry (how I used to do it). BUT there was only some Ubuntu core entries. Since I am using FDE backed by a TPM, I think my kernel is then managed by a snap package. Even if most interfaces (wifi, ethernet, trackpad...) were not working I managed to login into the desktop (same for X and Wayland) and had a terminal and the laptop keyboard working. (even though the laptop specific Thinkpad features were not functioning: no mute LED, no mic cut LED...). Once logged in, I checked kernel version and I was running kernel 6.8.0-56. I saw I had two available version of the kernel for pc-kernel snap: pc- kernel 6.8.0-54.56 rev 2247 and pc-kernel 6.8.0-56.58+1 rev 2352. I suspect pc-kernel 6.8.0-56.58+1 rev 2352 to be problematic. In order to fallback to the previous kernel, I reverted the current snap: ``` sudo snap revert pc-kernel ``` After a reboot: I have all my interfaces back with 6.8.0-54-generic and the problematic version disabled. ``` user@ThinkPad13gen2:~$ snap list pc-kernel --all Name Version Rev Tracking Publisher Notes pc-kernel 6.8.0-54.56 2247 24/stable canonical✓ kernel pc-kernel 6.8.0-56.58+1 2352 24/stable canonical✓ kernel,disabled ```
