Package: dh-python
Version: 5.20221001
Severity: normal
X-Debbugs-Cc: scho...@ubuntu.com

For instance, pylint has "tomli>=1.1.0;python_version<'3.11'" in its
pyproject.toml, which is translated as "python3-tomli (>= 1.1.0) |
python3 (>= 3.11)".

This means that if we have python == 3.11 but still have python3.10 in
the archive, any code that iterates over all supported archive risks
failing simply due to the tomli module missing.

This is currently happening in the distro-info autopkgtests for the
python3-defaults migration from unstable to testing (and also in
Ubuntu). I'll probably be adding tomli as a test dependency in Ubuntu as
a stopgap, but I figured someone might think of a better long-term
solution to the issue.
