Comment 43 for bug 1991606

Taking an Ubuntu docker image (or similar) and installing the latest pip/setuptools is a very common use case for CI pipelines and building containers. Since distro-info and python-debian are in most images, all those use cases are affected. The bug is that these Ubuntu packages violate the Python versioning. So we should fix the packages that are broken instead to work around them in other places.

So I suggest that we backport fixing the broken version numbers for distro-info and python-debian (but do not SRU the other affected packages). The security update for distro-info in bionic introduced the regression (0.18 was a valid version, but 0.18ubuntu0.18.04.1 is not).
