Bug#1021317: salt-master: Fails to start with "zmq.error.ZMQError: Invalid argument"

[Stijn Segers]

Hi!

Applying the fix linked in https://github.com/saltstack/salt/pull/62119 
resolves the ZMQ error, but unmasks another one - the 
salt.transport.base module. The base module is not part of 3004.1 (or 
.2). It was introduced with version 3005. Pulling the base.py file from 
https://github.com/saltstack/salt/tree/v3005/salt/transport doesn't 
solve it since Salt will start complaining about a missing 
'ZeroMQPubServerChannel' attribute.


I've checked the Debian package and it contains a lot of patches, so it 
looks like the Debian version is  heavily modified (diffing the 
upstream 3004.1 zeromq.py code against the Debian package zeromq.py 
confirms this).

I have the same issue, and python3-zmq on my system is 24.0.1-1.
