instead of trying to find the answer to why I can't log in, whether it be because of lightdm or Xauthority, I am just trying to update from 14.04 to 14.10. When I try to update it fails. Any help would be amazing.
When I do "do-release-upgrade" it goes through until it asks permission to commence with upgrade, at some point though it says aborting due to network connection. I am connected to the internet though.
Now as I cannot fix the original problem, nor can I upgrade, I decided to try to just clean install using "sudo dpkg-reconfigure -phigh -a" it started off working alright up until it came to the files /var/lib/dpkg/info/compiz.config it said not found for 15 different cases that it could not find said files.
