Package: python3-zmq
Version: 22.3.0-1
Severity: grave
I have issues updating packages nbconvert and jupyterlab-server, both
of which because of autopkgtest failures, with the similar-looking
backtrace:
autopkgtest [08:13:59]: test autodep8-python3: [-----------------------

The same error message is discussed here:
https://github.com/zeromq/pyzmq/issues/1460
but it looks like the error message in fact hides the real issue...
