This installation ran fine for about a week, but today it refuses to boot. I've tried several fixes from other questions, in particular https://askubuntu.com/a/1099111/333715. I've also tried install lightdm
instead of Wayland to no avail. journalctl -b-1
shows no obvious errors.
The really curious thing is that it the first time this happened, I booted into the Windows partition on the same drive to see if that still worked, then booted back to Ubuntu, which succeeded. However, it has failed every time since then.
Any other suggestions would be much appreciated.
