Hello, i set up a new uyuni and register my test systems. It was possible to registered the server successfully, but all the server are now inactive. After delete and reregistered again, only the salt-key is visible, but the system is not register successfully. After the delete I was also deinstalle the salt-minion, salt and python2-salt from the client and run the bootstrapscript again, without an error on the client side. The salt stack is working, I'm able to contact the minions from the salt-mast and across. The following os-systems are registered to Uyuni and has the same issue: OpenSUSE Leap 15.0 OpenSUSE Leap 15.1 OpenSUSE Leap 42.3 SLES12SP4 By the inactive and registered system it is possible to ask for the salt state from the client side: Salt-call state.highstate: local: ---------- ID: mgrchannels_repo Function: file.managed Name: /etc/zypp/repos.d/susemanager:channels.repo Result: True Comment: File /etc/zypp/repos.d/susemanager:channels.repo is in the correct state Started: 07:43:47.884492 Duration: 181.211 ms Changes: ---------- ID: /etc/pki/trust/anchors/RHN-ORG-TRUSTED-SSL-CERT Function: file.managed Result: True Comment: File /etc/pki/trust/anchors/RHN-ORG-TRUSTED-SSL-CERT is in the correct state Started: 07:43:48.066056 Duration: 1277.558 ms Changes: ---------- ID: update-ca-certificates Function: cmd.run Name: /usr/sbin/update-ca-certificates Result: True Comment: State was not run because none of the onchanges reqs changed Changes: ---------- ID: pkg_installed Function: pkg.installed Result: True Comment: No packages to install provided Started: 07:43:49.383607 Duration: 1.142 ms Changes: ---------- ID: pkg_removed Function: pkg.removed Result: True Comment: All specified packages are already absent Started: 07:43:49.385007 Duration: 1407.343 ms Changes: ---------- ID: pkg_latest Function: pkg.latest Result: True Comment: No packages to install provided Started: 07:43:50.792781 Duration: 0.797 ms Changes: ---------- ID: disable_spacewalksd Function: service.dead Name: rhnsd Result: True Comment: The named service rhnsd is not available Started: 07:43:50.795305 Duration: 17.72 ms Changes: ---------- ID: disable_spacewalk-update-status Function: service.dead Name: spacewalk-update-status Result: True Comment: The named service spacewalk-update-status is not available Started: 07:43:50.813411 Duration: 10.929 ms Changes: ---------- ID: disable_osad Function: service.dead Name: osad Result: True Comment: The named service osad is not available Started: 07:43:50.824714 Duration: 10.748 ms Changes: ---------- ID: remove_traditional_stack Function: pkg.removed Result: True Comment: All specified packages are already absent Started: 07:43:50.835840 Duration: 491.993 ms Changes: ---------- ID: mgr_mine_config Function: file.managed Name: /etc/salt/minion.d/susemanager-mine.conf Result: True Comment: File /etc/salt/minion.d/susemanager-mine.conf is in the correct state Started: 07:43:51.328156 Duration: 8.212 ms Changes: ---------- ID: mgr_salt_minion Function: pkg.installed Name: salt-minion Result: True Comment: All specified packages are already installed Started: 07:43:51.336736 Duration: 28026.016 ms Changes: ---------- ID: mgr_salt_minion Function: service.running Name: salt-minion Result: True Comment: The service salt-minion is already running Started: 07:44:19.363709 Duration: 30.719 ms Changes: Summary for local ------------- Succeeded: 13 Failed: 0 ------------- Total states run: 13 Total run time: 31.464 s
