ubuntu upgrade wants administrative password

Question

Aloha - when selecting 'Upgrade" for 11.10 (in this case) the app loads two files, provides an informational screen, then asks for me to "Enter the Administrative password." I know my username and password (which I use to make other changes) and I am the only user on the server, but my password does not work and I get kicked out after three attempts. What could this be?

Answer 1

What it wants is the password for root on the server. If you want to test this theory out then open a terminal and run sudo passwd root then enter a new password for root. Next time you try the upgrade enter the password you just set. The methods described by user58201 should work as well, but didn't exactly answer your question.

Answer 2

You could try one of two methods and see if it still prompts you for an administrative password. Method one is using Alt+F2 and typing sudo update-manager -d (might be sudo upgrade-manager -d). Method two is opening a terminal window, and typing sudo do-release-upgrade in.

Hope this helps. Have a great day:

Answer 3

I have same problem after fresh install and sudo update-manager from terminal worked
