I installed package icogen.deb from gnome-look.org (http://gnome-look.org/content/show.php/icoGEN?content=124870). After that I couldn'd neither launch that application nor remove it. Now I cannot install any software, when I try I get this message: Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/aptdaemon/worker.py", line 768, in simulate
    return self._simulate_helper(trans, status_path)
  File "/usr/lib/python2.6/dist-packages/aptdaemon/worker.py", line 936, in _simulate_helper
    return depends, status, self._cache.required_download, \
  File "/usr/lib/python2.6/dist-packages/apt/cache.py", line 218, in required_download
    pm.get_archives(fetcher, self._list, self._records)
SystemError: E:I wasn't able to locate file for the icogen package. This might mean you need to manually fix this package.

I use Ubuntu 10.10. How to remove that package manualy?
