[Python-apps-team] Bug#943516: valinor: FTBFS and autopkgtest failure due to new version of python-colorama

[Paul Gevers]

Source: valinor
Version: 1.1.4-1
Severity: serious

Dear maintainers,

With a recent upload of python-colorama the autopkgtest of valinor fails
in testing when that autopkgtest is run with the binary packages of
python-colorama from unstable. It passes when run with only packages
from testing. In tabular form:
                       pass            fail
python-colorama        from testing    0.4.1-1
valinor                from testing    1.1.4-1
all others             from testing    from testing

I copied some of the output at the bottom of this report. I also tried
to rebuild on reproducible-builds.org infrastructure and your package
FTBFS with the same error.

Currently this regression is blocking the migration of python-colorama
to testing [1]. Of course, python-colorama shouldn't just break your
autopkgtest (or even worse, your package), but the change in
python-colorama was intended and your package needs to update to the new
situation.

If this is a real problem in your package (and not only in your
autopkgtest), the right binary package(s) from python-colorama should
really add a versioned Breaks on the unfixed version of (one of your)
package(s). Note: the Breaks is nice even if the issue is only in the
autopkgtest as it helps the migration software to figure out the right
versions to combine in the tests.

[0] You can see what packages were added from the second line of the log
file quoted below. The migration software adds source package from
unstable to the list if they are needed to install packages from
python-colorama/0.4.1-1. I.e. due to versioned dependencies or
breaks/conflicts.
