Public bug reported:
After not touching my notebook since 30th September (where I did the
dist-upgrade to artful and installed all available updates), I did all
available updates today (20th October) and the system didn't boot after
that.
The last message I see is "Reached target Bluetooth". Before that, there
are several failed services. GDM doesn't come up.
After logging in on tty2, I saw that the root partition was mounted
read-only. Inspecting the messages of e.g. systemd-resolved shows that
it didn't start because of the read-only filesystem. After remounting it
fw, I was able to restart the daemons and could also start GDM and login
fine.
My fstab shows:
UUID=a936dbe9-5ab5-4272-aaae-d22030824373 / ext4 errors
=remount-ro 0 1
The UUID is correct as "mount / -o remount,rw" works fine. Booting with the
previous kernel doesn't change anything.
