Hi Martha, I am a bit reluctant to go in that direction for two main reasons:
Despite github workflow are free for today, nothing guarantees it remains free (appveyor and travis used to be free). So I am in favor of keeping CI as small as reasonable, with the idea of not wasting our generous donators' money.
Environmental cost: once a while would be enough, no ?
But I am open to discussion...
Basically, this PR adds running the debian package script to the ubuntu GitHub action. This required some adjustments...
