Hi, we had to move several SLES15 systems to another network behind a firewall. Therefore we changed the respective files ifcfg-eth0, route and hosts and reloaded wicked. Access to repositories works fine but the service salt-minion shows: “Error while bringing up minion for multi-master. Is master at lkv-srvapp39.lkvbay.net responding?” (lkv-srvapp39 is the only Uyuni system) Any idea? Uyuni is release 2021.06. We used the workaround that Julio Gonzalez described at 01.04.22 and applied the patches of the salt packages only at the Uyuni system. Gruß, Tobias Crefeld.
