Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/202512/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:aiozmq, so that this is still
visible in the BTS web page for this package.

Thanks.

This seems non-trivial to fix; even if some other event loop policy
might work, the whole event loop policy system is deprecated and will be
removed in Python 3.16 according to
https://docs.python.org/3/library/asyncio-policy.html, so this really
needs an active upstream maintainer to do whatever redesign is
appropriate.  Unfortunately, there've been no upstream commits for over
three years (see also https://github.com/aio-libs/aiozmq/issues/191).

I don't see any reverse-dependencies in Debian, so I wonder if it's time
to just remove this package?  CCing the Python team and Piotr (who
originally added this package) for second opinions.

Thanks,
