Source: dnspython
Version: 2.7.0-1
Severity: serious
User: debian...@lists.debian.org
Usertags: regression
User: debian-s...@lists.debian.org

X-Debbugs-CC: debian-s...@lists.debian.org
Dear maintainer(s),
With a recent upload of dnspython the autopkgtest of dnspython fails in
testing when that autopkgtest is run with the binary packages of
dnspython from unstable on s390x. It passes when run with only packages
from testing. In tabular form:
pass fail
dnspython from testing 2.7.0-1
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 to testing [1]. Can
you please investigate the situation and fix it?
More information about this bug and the reason for filing it can be found on
