Installed Isis, twice, because of this issue which I discovered when doing "sudo apt-get update"
All the "deb http://gb.archive.ubuntu.com/ubuntu/ trusty main restricted deb-src http://gb.archive.ubuntu.com/ubuntu/ trusty main restricted" had "Isis" instead of "Trusty" so I couldn't get any packages from the main Ubuntu repositories.
