Dear maintainer(s),
With a recent upload of redis the autopkgtest of python-fakeredis fails
in testing when that autopkgtest is run with the binary packages of
redis from unstable. It passes when run with only packages from testing.
In tabular form:
pass fail
redis from testing 5:7.0.8-2
python-fakeredis from testing 1.9.0-0.1
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 redis 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
https://wiki.debian.org/ContinuousIntegration/RegressionEmailInformation
