Ok, you can't exactly skip OS's from the Update Manager. So you have to boot from a Ubuntu 12.04 ISO file (Via a CD, for example.).
These are the ways to install the ISO:
Live CD: Follow the steps!
USB installer Again, follow the steps!
Stand-Alone Installer: Install then follow the steps!
Of course you can easily install 12.04 from scratch.
Mind you: 12.04.2 is out and I'd like to suggest that you download and install this version. It has all released updates inside the ISO + has a newer kernel (3.5) and X-server.
I wouldn't go for an upgrade since the changes are severe compared to 11.04.
Keep in mind with the required hardware specifications ! Having for about 1.5 Gb RAM-memory is certainly nessecary for a good work-flow (my own standards).
If you have less RAM I'd go for Xubuntu, what will run far better than Ubuntu (Unity).
