No longer works without snap on Ubuntu OS.

[aFraley]

According to this blog post and other sources out there, chromium-browser is no longer usable from the apt-get install method. They're forcing everyone to use snap instead. Trying to run chromium-browser form the apti-get install results in this message in the terminal:

chromium-browser --help              

Command '/usr/bin/chromium-browser' requires the chromium snap to be installed.
Please install it with:

snap install chromium
