Comment 2 for bug 668977

hey the problem got fixed..
the following was the detailed error i was getting from aptdaemon::

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 mysqmail package. This might mean you need to manually fix this package.

i entered the following code in the terminal
                                       sudo apt-get install mysqmail

and rebooted..
all working fine now... (:
