Long story short, I tried installing something via apt-get install and accidentally terminated the process through terminal. I now can't use apt-get install, Ubuntu Software Center, etc. I tried running sudo apt-get clean and sudo apt-get autoclean, but to no avail.

I then tried running sudo apt-get install -f, and got the following results:

    Do you want to continue [Y/n]? y

E: Sub-process /usr/bin/dpkg returned an error code (1)

How can I fix this error, or at least "reset" apt-get so I can install things again?
