Can't install or uninstall anything in Ubuntu - Processing was halted because there were too many errors

Question

I tried to install and uninstall many different programs. For example:

sudo apt-get remove --purge ussp-push

Or

sudo apt-get purge ruby

And everytime I get this output in my terminal. This seems to have started after I tried installing MongoDB on my machine.

I got the same error and this command helped me out

dpkg --configure -a
