The screen shot says it all. I got an automatic upgrade pop up to update the OS to 12.04 from 11.10. It worked fine for an hour or so and for past hour it's stuck at "About 4 minutes remaining" screen.
In the background terminal, the "top" processes are shown.
This question is not answered satisfactorily anywhere as the release is pretty new.
What is the best way to deal with this situation ?
Additional info: I am seeing some of my software programs like remmina, firefox, google-chrome are having some new looks and may be other apps to. Does it mean that, everything has went fine and the box shown in figure is just a spurious message ?
