Dear maintainer(s),
With a recent upload of uwsgi the autopkgtest of uwsgi-plugin-python
fails in testing on s390x when that autopkgtest is run with the binary
packages of uwsgi from unstable. It passes when run with only packages
from testing. In tabular form:
pass fail
uwsgi from testing 2.0.31-4
uwsgi-plugin-python from testing 0.0.2
all others from testing from testing
I copied some of the output at the bottom of this report.
Currently this regression is blocking the migration of uwsgi to testing
[1]. Due to the nature of this issue, I filed this bug report against
both packages. Can you please investigate the situation and reassign the
bug to the right package?
More information about this bug and the reason for filing it can be found on
