Install and run .deb packages using toolbox

I second this. My main concern is how the article is going to be written if we start right away. There’s no official Debian/Ubuntu toolbox like there is for Fedora so we can only promote unofficial methods. I wrote a Dockerfile just a couple of days ago to test things out, and it seemed to work. But that’s of course an unofficial solution.

There’s also an open merge request in the Toolbox repo for adding a Debian Sid image, but there hasn’t been an update yet.

I suggest we wait until Debian or Ubuntu gets added so we can write a proper article.
