I tried to upgrade my Ubuntu Server following these instructions:
http://www.ubuntu.com/desktop/get-ubuntu/upgrade
But the command do-release-upgrade (as root) brings me:
Checking for a new ubuntu release
Failed Upgrade tool signature
Failed Upgrade tool
Done downloading
extracting 'intrepid.tar.gz'
Failed to extract
Extracting the upgrade failed. There may be a problem with the network or with the server.
Actually running hardy.
Any ideas?

Step 2 of the official Ubuntu tutorial is misleading. Do not change the prompt to normal, leave it as is and it works.
It will work this way, if you are updating vom Hardy.
