Firstly I tried to install the 12.04 upgrade via the update manager GUI from 11.10 after there was no more updates to install and after a fresh reboot but all that would happen is it would say downloading release upgrade tool then that it is nothing else.
So I tried running this from the terminal\command line
brown@brown-Ubuntu:~$ update-manager -d brown@brown-Ubuntu:~$ do-release-upgrade Checking for a new ubuntu release Err Upgrade tool signature Connection failed Get:1 Upgrade tool [5612 kB] Fetched 5612 kB in 0s (0 B/s) WARNING:root:file 'precise.tar.gz.gpg' missing Failed to fetch Fetching the upgrade failed. There may be a network problem.
Can someone please help me out here.
