I'm on a new install of 20.04 and CHIRP is working fine (for me) after those minor patches for Python3 and GTK syntax. I didn't have to jump through any hoops to install prereqs. Actually, I think pyserial was the only thing I needed to install.

I tried running my fork in a fresh 18.04 VM, and only needed to install `future` and `serial`. Unfortunately I don't have a way to test on other platforms (e.g. Windows).

Note that I am operating from the py3 branch, so maybe some work was already done there to remove the problematic dependencies you mentioned.

So the rabbit hole extends outside the codebase and IMO won't help users who are not upgrading from an older Ubuntu install. (Did you upgrade or install fresh?)

For instance, it's not feasible for the everyday chirp user to collect all of the dependencies needed for chirp to run on Ubuntu 20.04 from a fresh install because many of those packages aren't in the focal fossa repo.

For instance, try to apt install python-libxml2 python-gtk and you may see a message like "couldn't find package xyz but is referenced by another package" from apt.
