How do I upgrade from 10.04 or 11.10 to 12.04?
I am running Ubuntu 10.04 and I am very interested in upgrading to the new 12.04, but my update manager won't recognize that the new version is out apparently because when I run it.. all it says is that the newest version is 10.10 and that it isn't supported.... I am fairly new to using Linux Ubuntu OS and already I love the freedom I get from it.. I would greatly appreciate it if you at Ubuntu could help me make the most of my experience.. Please help me understand why I can't automatically upgrade to 12.04 or atleast 11.10.
Thank You for your time in reading this,
