[Bug 659438] Re: Installation/Removal fails because of package which could not be located (failure in apt.Cache.required_download)

[mindaugz69]

I tried all suggested solutions ("I did an update on ubuntu and was then
able to install my programs."; "sudo apt get-remove & apt get-update &
apt get-upgrade"; "apt-get --configure -a";  i have installed aptdaemon
0.41"; "sudo bash (your password) apt-get update & & apt-get upgrade";
"dpkg -C" - i know broken package, but i dont know how to remove it;
"sudo dpkg --configure -a"; "sudo apt-get update then sudo apt-get
install"; "I did manage to fix several issues with the Unity-Desktop via
'Compiz-Manager' - such manager is unavailable in ubuntu 11.04 classic
and CompizConfig Settings manager doesn't help anyhow"; ), but the
problem still persists:

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 961, in simulate
    trans.unauthenticated = self._simulate_helper(trans)
  File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 1085, in _simulate_helper
    return depends, self._cache.required_download, \
  File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 226, in required_download
    pm.get_archives(fetcher, self._list, self._records)
SystemError: E:I wasn't able to locate file for the gnome-mplayer package. This might mean you need to manually fix this package.

I'm using Ubuntu 11.04. Could anyone help to solve this problem?
