Hi Viktor, your hint with the version of python3-salt made me think about downgrading it, which was successful. zypper in --oldpackage python3-salt-3000-30.1 and accepting the dependent downgrades of the packages of salt and salt-minion makes service salt-minion work again. It seems that Patch SUSE-15-SP2-2021-2106 is responsible for dysfunction of the service salt-minion. BTW: Is there a way to block a patch from being activated in general? Regards, Tobias Crefeld.

Are there any tweaks in the minion configs? On Mon, 2021-07-12 at 15:49 +0000, Crefeld, Tobias LKV Bayern e.V. wrote: Hi Victor, thanks for your fast reply!

What is the salt version installed on the minion. It's better to check the output of: zypper se -s salt Regards, Victor
