You could try using alien and convert the RPM’s to DEB’s and see if that works. I have not tested this personally so not sure if it would work or not, but worth a shot.
I will spin up an Ubuntu 20.04 box and see if I can see anything that might look odd. While doing that going to ping the Atix guys to see if they know of any things that could stand out or be missed since I have not done much in the DEB land.
