Public bug reported:
This is happening on fresh Ubuntu 20.10 install with just nvidia drivers
and a few cmd utilities installed. When I try to rollback to any
previous snapshot from grub menu, Ubuntu never rolls back to that
snapshot.
I choose a previous snapshot form grub menu, history submenu (doesn't
matter if system only or system with user data). OS starts to boot, low
res plymouth shows up but the OS never finishes booting. When I press
ESC to see whats going on, the boot process is stuck at "Reached target
sound card". If I press CTRL+ALT+DEL computer restarts and OS boots up
normally into the last state it was in. That is the filesystem didn't
rollback. When I inspect the zfs datasets with "zfs list" and "zsysctl
show" there is a new dataset in rpool "rpool/ROOT/ubuntu_". A dataset
without a suffix. Unfortunately I couldn't find anything in journalctl
and I don't know where to look for more logs.
Now, if I choose to rollback to a snapshot in recovery mode the OS boots
up but the file system is in some broken state. For example missing
packages, snaps not working. Zsysctl shows that current dataset is a
dataset without suffix (rpool/ROOT/ubuntu_). I guess the filesystem is
in broken state because the other datasets under ubuntu_xxxxxx didn't
get mounted or something.
This time I found something in journalctl logs.
