I recently upgraded a machine from 12.10 to 13.04 and while nothing appears to be broken, I have an odd issue. When I ssh into the machine, I get the following message:
That seems a bit contradictory. I tried running do-release-upgrade but it doesn't do anything:
Welcome to Ubuntu 13.04 (GNU/Linux 3.8.0-19-generic x86_64)
* Documentation: https://help.ubuntu.com/
New release '13.04' available.
Run 'do-release-upgrade' to upgrade to it.
Any thoughts? I'm just worried the upgrade may be incomplete or something.
Checking for a new Ubuntu release
No new release found
