Python library `distro==1.8.0` does not work with `fpm`

[spkane]

Python library distro==1.8.0 does not work with fpm and therefore breaks the build-scripts/ubuntu-2004/build-3rd-parties.sh script, without first doing something like this:

sed -i 's|build_from_pypi distro|build_from_pypi distro 1.7.0|g' ./build-scripts/ubuntu-2004/build-3rd-parties.sh

• https://pypi.org/project/distro/#history

It appears that this is due to the removal of setup.py which fpm requires. Some projects appear to be trying to replace fpm with https://github.com/upciti/wheel2deb as a solution.

https://github.com/hyperledger/indy-node/pull/1787 fixes the immediate issue reported here. Long term we'll have to look into aligning with the new setuptools recommendations, as noted in the distro v1.8.0 release, and the use of https://github.com/upciti/wheel2deb as noted above.
