Can't upgrade from 11.10 to 12.04

[kyng]

When I click upgrade in Upgrade manager it downloads 2 files, asks for root psw and then nothing happens. Upgrade managee is closed and there are no error messages or anything so I have no idea what is wrong. Any sugestions?

Well, I never recommend upgrades, (too much trouble, for me), but if you want to do that, there may be some debugging output from update-manager.

Try:


update-manager

from the terminal.

Or boot the computer and run


sudo apt-get update
sudo apt-get upgrade

as they give more detailed error messages.

If it does not work, don't waste too much time. A fresh install is always worth considering.

what updates are installed ?

open software-center -> History -> updates .

Or boot the computer and run


sudo apt-get update
sudo apt-get upgrade

As OP wants to upgrade from one release to another, why will this help? Just wondering, a little confused. :-k

Before trying the online upgrade it's important to verify that the system is stable and receives the normal updates.

sudo do-release-upgrade -dThat did the trick. This problem is solved I guess.

That worked for me as well.

Thanks for the tip!!!
