NOTE: Linux Mint 'tara', 'tessa', 'tina', and 'tricia' are based on bionic
NOTE: Most of the time, binaries compiled on 18.04 will work on newer
releases, meaning you can try adding newer releases to the bionic conditional
(e.g. 'disco|bionic|juno|...'), to support installation on a newer system;
however, do this 'at your own risk', as not all features will be guaranteed to work.
