You recently added an autopkgtest to your package multiplex, great. However, it fails. Currently this failure is blocking the migration to testing [1]. Can you please investigate the situation and fix it? I copied some of the output at the bottom of this report. I'd like to remark that s390x is our only big-endian release architecture, maybe that's related here? =================================== FAILURES =================================== ___________________________ test_async_stream_reader ___________________________
