Cannot install any software from the Software Center due to mss-ttcoreconts package error
I'm trying to install packages and I get this error:
There seems to be a programming error in aptdaemon, the software that allows you to install/remove software and to perform other package management related tasks.
and the details:
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 968, in silmulate
trans.unauthenticated = self._simulate_helper(trans)
File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 1092, in _simulate_helper

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 ttf-mscorefonts-installer package. This might mean you need to manually fix this package.
How do I resolve this error?
