Apt-get broken after termination in mid-install

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
    debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable

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?

Solution 1:

You can fix this by just run dpkg --purge --force-depends "package_name" to purge a broken package then you have to run apt-get autoremove and apt-get -f install After this, the problem will be solve.

Solution 2:

Just reboot the machine. Whatever is using that file should no longer be using it after a reboot. Then run sudo apt-get install -f to repair it. That should work for ya.
