apt-get is a utility that looks for PACKAGE NAMES. It is not meant to look directly at file names. It was originally a 'shell' for a program called dpkg and that was meant to be used with deb files, and this is how Debian linux files are still distributed. Now, apparently, Red Hat has a port that lets you hunt down RPMs, which is cool.
IF (not in this case) you had a .deb file downloaded, you would run
dpkg -i filename.whatever.deb
