Why is the Update manager of my Ubuntu 11.04 say "There are no updates to install"?
And no message "New Ubuntu release '11.10' is available" is displayed?
In software sources it is set to "Normal Releases".
What am I missing?
It's possible that Update Manager is checking for LTS releases only or no releases. In software properties (sudo software-properties-gtk
), on tab Updates, check the last option - Release upgrade. It should be set to Normal releases.
Also try running sudo update-manager --check-dist-upgrades
and make sure you have all packages up-to-date (especially for Update Manager).
There are more upgrade strategies at https://help.ubuntu.com/community/OneiricUpgrades
If nothing of this helps, try updating package information from console - what's the output of sudo apt-get update
command?
Edit: The Maurizio's problem was caused by outdated mirrors. The mirror can be changed in Software Properties on the first tab, in Download from select Main server.
First go in your file /etc/apt/sources.list
logged as root and check of all main ubuntu packages didn't have # at the beginning of line. If yes, remove the #'s.
Then do sudo apt-get update
And finally sudo apt-get dist-upgrade
If it finds new packages, mainly the kernel modules, and you install them, you will get the new ubuntu.
cat /etc/issue
and post what you got.
There is a choice in software sources if you want to be notified of normal releases or just LTS releases. Perhaps you've opted to only be notified of LTS releases?
