Louis What are you using postresql for? Do you have any particular "sensitive" databases on it? If so, seek help on how to backup databases before continuing.
It looks to me like this error is somewhat historical, i.e. it was an upgrade that failed a while ago (due the the old version number). I am pretty confident that allowing the system to do a full upgrade will sort out the problem. sudo apt-get update && sudo apt-get dist-upgrade ... should rebuild the package lists and solve dependency problems... hopefully :) -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
