I have had an install that was very stable for like 6 months this morning I did update my install everything was fine while I was using it. Then it fails to boot after trying to start later in the day.
In emergency mode I can not type in the shell. But I noticed when it lists the uuid of the device it has a square character like there's some corruption or something.
Would anyone know if that's normal or a sign that somethings messed up?
Also are the next steps to go make installer usb then diagnose further.
Other info idk if is needed running a btrfs file system and do have snapshots that were setup but can't get into anything to Role those back
