Cannot install any software from the Software Center due to ttf-mscorefonts-installer package error

Ubuntu 11.10

Software Centre

Error title:An unhandlable error occured

Error Body:

 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.

Details: Traceback (most recent call last):

    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.

What should I do? Sorry if this has been posted before.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

please add the output of sudo apt-get -f install followed by sudo apt-get update && sudo apt-get upgrade –  fossfreedom Dec 21 '11 at 21:49

It happened to me today and got solved. Unfor. I didn't catch the whole process... I issued the first command fossfreedom suggested. It returned 1 package not updated. Then the second - one package got updated, software center wouldn't even start after that. I used sudo apt-get install clipit to install something and see what's going on (without using the USC). Clipit got installed no problem. I restarted my computer and now it's all fine. Sorry for not being any more helpful and thank you fossfreedom for your input!

I fixed the issue myself. It was an issue with a botched install of a fonts package. I will delete the question shortly. Thanks for your input though. I realized what the problem was almost immediately after posting. It was the mss-ttcorefonts package.

I went into synaptic and went into the list of broken packages. I renistalled and have no problems now.

IMO that would be a bad thing to do. I myself stumbled upon the question following the exact same error message. –  Bucic Dec 22 '11 at 23:44
