[Debian-med-packaging] Bug#1013275: toil: FTBFS with Python 3.10 only

[Graham Inggs]

Source: toil
Version: 5.6.0-6
Severity: important
Tags: ftbfs

Hi Maintainer

Toil hardcodes python3.9 and will FTBFS when Python 3.10 is the only
supported Python version.  I've copied what I hope is the relevant
part of the log below, which shows the python3.10 tests being
attempted with python3.9.

Regards
Graham
