Hi @sinewave ,
4.6 is still in the RC phase I believe, so I would go to 4.5. You’ll need to upgrade version-by-version up to 4.5.
The pulpcore workers are numerous and there can be any number of them. That’s what the @* sign represents, essentially. You’ll likely have one worker per CPU core. So, you should see pulpcore-worker@1, pulpcore-worker@2, …
Were any of your workers running? Try running systemctl restart pulpcore-worker@* --all if they aren’t.
On my system, I have /etc/systemd/system/pulpcore-worker@.service
