Running into the same issue on a years old installation. Any ideas how to fix?

What Salt master version?

I ended up using Salt from the Rocky repo (3005) instead of 3007 from the Salt repo.

Mmm a reboot did some of the job. I found a bunch of reports elsewhere that 3007 changed the permission model to run more salt components in userland instead of as root, which more or less leaves /var/run/salt in a broken state until a full restart.

Minion still broken on the master though, looking into that now.

Minion is still spamming tons of errors but resumed working on its own shortly after reboot:

2024-06-18 08:50:05,586 [salt.transport.zeromq:396 ][ERROR   ][776] Exception while running callback

TypeError: object NoneType can't be used in 'await' expression

I can confirm this is still an issue on Ubuntu 22.04 and 3007.1. I originally submitted this bug under CentOS in my home environment but ran into the issue at work as well on a clean server.

I attempted fixing it with:

sudo rm -f /var/run/salt/master/master_event_pub.ipc sudo systemctl restart salt-master

But that did not work. Like you said, a full reboot brought the service back to a healthy state.

I'm seeing the same issue. Both salt server and minion are on v3007.0 on Rocky Linux 8. Rebooting both didn't clear messages.
