I've been trying to install some applications like Skype and Windows, yet same error message keeps showing

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.

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 ttf-mscorefonts-installer package. 

This might mean you need to manually fix this package.

I'm a newbie to Ubuntu and couldn't get it fix. I tried to search for similar questions yet couldn't really fix it.

This seems to be the error:

E:I wasn't able to locate a file for the ttf-mscorefonts-installer package.

Try to reconfigure unpacked packages first.

sudo dpkg --configure -a

And then install it:

sudo aptitude install ttf-mscorefonts-installer
