I am having problems with installation with everything in the software center.

Traceback (most recent call last):

  File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 968, in simulate

    trans.unauthenticated = self._simulate_helper(trans)

  File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 1092, in _simulate_helper

    return depends, self._cache.required_download, 

  File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 235, in required_download

    pm.get_archives(fetcher, self._list, self._records)

SystemError: E:I wasn't able to locate a file for the sun-java6-jre package. This might mean you need to manually fix this package.

Help?
