update-manager: upgrade to 15.04 rather than 16.04



I want to perform an upgrade from 14.04 to 15.04.
When I run "sudo update-manager -d" I get "... However, Ubunutu 16.04 LTS is now available(you have 14.04)" I think that this nighly build 16.04 is not yet stable.

How to upgrade to 15.04 and not 16.04?



Use update manager without the "-d" option. See man update manager for details.



The -d option means update to development release.




-d, --devel-release
Check if upgrading to the latest devel release is possible





http://manpages.ubuntu.com/manpages/precise/en/man8/update-manager.8.html



or run



sudo do-release-upgrade


See How to Upgrade from 14.10 to 15.04
