I am using 11.10 and I really want to update to 12.04 but it's impossible. I cannot see it in the update manager (I did select the option for the releases). I tried sudo update-manager d, and sudo-apt get upgrade and sudo apt-get upgrade release d but nothing. And sudo do-release-upgrade is not working as well! (I get "no release found" message.)

So finally I did put on a live USB and when I boot, I click on install, then it's telling me that I do have 11.10 and I can select for erase all and install Ubuntu 12.04 or I can install along 11.10 and the second option to update 11.10 to 12.04 is grey. I cannot selected it! Why? Am I running out of options?

What else can I do to upgrade to 12.04?

Ok, what's the output of cat /etc/update-manager/release-upgrades? – SirCharlo May 04 '12 at 18:30
@SirCharlo Default behavior for the release upgrader.
[DEFAULT] # determine if a newer release is available. prompt=lts

Ok, then try sudo sed -i 's/lts/normal/g' /etc/update-manager/release-upgrades; sudo do-release-upgrade – SirCharlo May 04 '12 at 18:36
Why are you trying to upgrade to 12.10? Latest release is 12.04, and I think that 12.10 is in a too early stage to be tested – Stefano May 04 '12 at 18:47
@Pisu yeah sorry i tried to install 12.04 sorry and not 12.10 – Marco May 04 '12 at 18:53
