I got part way through an upgrade to 15.04 when we had a power cut to our street. The power was only off for a few seconds but it rebooted the computer when it was only partially upgraded. I've managed to use recovery mode to complete the installation (or I think it is). So now when I type
dpkg --configure -a nothing happens and when I type apt-get upgrade it says the system is up to date with 0 packages need updating, installing or removing.
However when I try to boot the computer it hangs. Grub comes up and then I get a brief message appear saying "starting version 219" but then I just get a white screen.
I've tried
systemctl enable sddm.service -f from recovery mode but I get an error message
Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1) repeated three times. I've read that this can be caused by drives referred to in fstab, so I looked in that and commented out the only drive in there which wasn't already commented out. This made no difference to booting up, still just get the white screen and it hanging at that point.
Since editing fstab to comment out that drive it now doesn't seem possible to mount the file system as read/write from recovery mode. Now when I try to edit fstab it says that it's read only and if I run
systemctl enable sddm.service -f I get the same error as before and also ones saying that it can't do various things because it's a read-only filesystem. So now I not only have a problem with my display manager not working but I also have a problem with the filesystem being mounted as read only, and since fstab is on that filesystem I can't even edit it to change it back!
What can I try now?
