package ttf-mscorefonts-installer (not installed) failed to install/upgrade: new ttf-mscorefonts-installer package pre-installation script subprocess was killed by signal (Terminated)

Was trying to install stuff to run video/install video player, failed, had to physically kill process. Running Ubuntu 20.04LTS. I'm sorry, I can't remember all the details, just that nothing worked in terminal and then I received a notification saying something had failed and I should do a partial upgrade - which also failed because of this process running.
