Right way to submit patches for Ubuntu packages

[Dan Kegel]

In a similar vein, my ppa
https://launchpad.net/~dank/+archive/ubuntu/python-fixes has a couple
cherrypicked fixes for the python ecosystem in ubuntu 16.04 and 18.04.
I put that together as I was fixing
https://github.com/nexB/scancode-toolkit to install via system pip;
turns out there were a couple problems that could not be fixed without
a couple fixes in ubuntu's python packages.

Any advice for the next step in navigating
https://wiki.ubuntu.com/StableReleaseUpdates ?
Or is a word to a python maintainer more appropriate?

Thanks,
Dan
