I think this is may be a silly question but, I keep asking, I have Ubuntu 12.04 which I have just upgraded to 14.04 using:
apt-get install update-manager-core
do-release-upgrade --check-dist-upgrade-only --devel-release
I' m running a web mail server on it which made me think of switching to Ubuntu Server for security issues.
But I have two questions, First does it come with interface, I mean not only Console, and Second and the most important, can I do that from Terminal or I have to format again and lose all my work?.
