I would like to upgrade to Ubuntu 15.04 from Ubuntu 14.04.2 LTS. I went in the terminal, edited the /etc/update-manager/release-upgrades
file, and set the prompt to normal. I went back into the terminal, and ran the command sudo do-release-upgrade -c
, and this is the output:
Checking for a new Ubuntu release
New release '14.10' available.
Run 'do-release-upgrade' to upgrade to it.
How can I upgrade to 15.04 without going to 14.10?
