hey all, i just switched from KDE to GNOME Ubuntu,
i understand basically how to use package managers and such but for some reason i cannot install anything
this is the error:

Traceback (most recent call last):
File "/usr/lib/python2.6/dist-packages/aptdaemon/worker.py", line 126, in _process_transaction
self.install_packages(self.trans.packages[0])

self._commit_changes()
File "/usr/lib/python2.6/dist-packages/aptdaemon/worker.py", line 551, in _commit_changes
changes = self._cache.get_changes()
File "/usr/lib/python2.6/dist-packages/apt/cache.py", line 179, in get_changes
for pkg in self:
File "/usr/lib/python2.6/dist-packages/apt/cache.py", line 161, in __iter__
yield self[pkgname]
File "/usr/lib/python2.6/dist-packages/apt/cache.py", line 154, in __getitem__
pkg = self._weakref[key] = Package(self, self._cache[key])
KeyError: 'kipi-0lugins-doc'


any help would be appreciated
