Oh I'm silly, one sec.

Hmm ok this problem seems to be more complex, since we need to check the distro in a function that tries to obtain the distro to begin with. In this line, $distro_shorthand is either "on", "tiny", or "*", and $distro is not assigned yet.

so I used $(lsb_release -si) to check for the distro instead.

if [[ -f /etc/debian_version ]] && [[ $(lsb_release -si) != *"buntu"* ]]; then

Also, would it be better to check if the distro is Debian instead of if the distro isn't Ubuntu here?

I'm trying to remember my reasoning for checking that it's not Ubuntu vs checking that it's specifically Debian, and can't come up with anything at the moment. I think it would be better to check if it's specifically Debian.
