Re: Can't install anything, please help!

Those commands works fine, but then, the same, the password prompt does not appear for update manager or software manager.

There were shown 0 updates because I have the latest versions.

0 upgraded, 0 newly installed, 0 to remove and 448 not upgraded.
kubuntu-desktop is already the newest version.

I think this is a bug, no doubt. On fedora with kde, the password prompt appears.

Here I have installed Ubuntu first, then KDE:

Same on a kubuntu installed from iso in virtualbox. Ubuntu software center, Muon software center and updates doesn't work, because the password prompt does not appear.

Now I have installed Kubuntu directly from iso in virtualbox and works, the password prompt shows.
I think the problem is at kubuntu installed with wubi.
