Following the guide I found here I am trying to upgrade my Ubuntu version from 10.10 to 12.04.
do-release-upgrade gave the error command not found I tried to install
update-manager-core which results in this error
root@myserver:~# apt-get install update-manager-core Reading package lists... Done Building dependency tree... Done E: Unable to locate package update-manager-core
Now I'm stuck, as nobody else on the web seems to have that issue
