Yesterday I upgraded a machine from 12.10 to 13.04 using the GUI from
the update-manager. Something mysteriously died towards the end (I
got some /var/crash/_whatever) & I can't figure out how to tell if the
upgrade worked or not. When I log into the machine it shows this:
Welcome to Ubuntu 13.04 (GNU/Linux 3.8.0-19-generic i686)
Graph this data and manage this system at https://landscape.canonical.com/
New release '13.04' available.
Run 'do-release-upgrade' to upgrade to it.
But do-release upgrade does nothing:
/home/xxxxx $ sudo do-release-upgrade
[sudo] password for xxxxx:
Checking for a new Ubuntu release
No new release found
and aptitude update && aptitude safe-upgrade do nothing either. I've checked that all the entries in /etc/apt/sources.list and sources.d/*.list have "raring".
How do I verify that my system is upgraded? If it is, how do I fix the "New release" message?
