Removing ttf-mscorefonts-installer

The package ttf-mscorefonts-installer is showing up in Update Manager as having been downloaded but not installed. When I run sudo apt-get remove ttf-mscorefonts-installer I get the message

 dpkg: warning: there's no installed package matching ttf-mscorefonts-installer:amd64

I can't uncheck the box next to ttf-mscorefonts-installer in the Update Manager interface, and I can't install any other updates because I get the error message

Requires installation of untrusted packages

The action would require the installation of packages from not authenticated sources.

How do I get rid of ttf-mscorefonts-installer so that it stops causing problems?

First trying this ->

sudo apt-get update
sudo apt-get -f install

If it doesn't fix the problem, try removing the package with

sudo dpkg -r ttf-mscorefonts-installer

Hope it will help.

Try

sudo apt-get remove --purge ttf-mscorefonts-installer

EDIT: remove --purge is equivalent to the purge command which removes configuration files along with the package.
