Dear maintainer(s),
With a recent upload of pyyaml the autopkgtest of lava fails in testing
when that autopkgtest is run with the binary packages of pyyaml from
unstable. It passes when run with only packages from testing. In tabular
form:
pass fail
pyyaml from testing 5.3.1-4
lava from testing 2020.12-3
all others from testing from testing
I copied some of the output at the bottom of this report. It seems that
Ubuntu already has a patch since half of April [0].
Currently this regression is blocking the migration of pyyaml to testing
[1]. Of course, pyyaml shouldn't just break your autopkgtest (or even
worse, your package), but it seems to me that the change in pyyaml 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 pyyaml 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.
