> To upgrade from Ubuntu 10.04 LTS on a server system: install the update-manager-core package if it is not already installed; edit /etc/update-manager/release-upgrades and set Prompt=normal; launch the upgrade tool with the command sudo do-release-upgrade -d; and follow the on-screen instructions.
10.10 doesn't provide much over 10.04 for a server, so people should wait maybe? I installed the 10.10 RC a little while ago on my primary machine but I am on 9.04, 9.10 and 10.04 on various other machines.
Yeah, I'd strongly recommend sticking with 10.04 LTS for any production servers -- unless you require a particular and/or peculiar feature in 10.10, that is.
LTS == Long Term Support == security fixes for 5 years. :-)
