Hello everyone, thanks for your replies, it turns out that in the end
the system had just munched itself as Tony said. I decided since Its
so badly out of date, and as its just a file server, I'm going to move
all the stuff onto one of my TB drives, install the new version of
Ubuntu and put it all back. Thanks for your advice everyone. :)
