I'm trying to upgrade my 10.04 server using do-release-upgrade, but it keeps saying there is no new version available.

If I change the prompt config in /etc/update-manager/release-upgrades to normal, I am able to upgrade to 10.10 though, but I don't want to perform 4 separate upgrades in order to reach the new lts.

Even though the release was already out, I still had to pass the "-d" parameter, then it worked fine. – skerit Jul 16 '12 at 9:57
