DNF Automatic ignores the foreman-protector plugin in Red Hat Satellite 6

Solution Verified - Updated -

Environment

  • Red Hat Satellite 6.15 and earlier
  • Red Hat Satellite Capsule 6.15 and earlier
  • Red Hat Enterprise Linux 8

Issue

  • When the dnf-automatic package is installed and configured on a Red Hat Satellite\Capsule 6 server, It applies all available package updates during the scheduled execution despite the foreman-protector plugin being enabled at dnf\yum level, leading to an unwanted service outage of the application.

Resolution

  • This issue has been reported to the Red Hat Engineering team via JIRA SAT-27276 and will be fixed in a future release of the product.

  • NOTE Meanwhile, Automatic OS updates are neither recommended nor supported to be configured on a Red Hat Satellite or Capsule server.

    • If it's configured and OS packages got updates, then make sure to execute the satellite-installer command and wait for it to complete successfully.

    • Lastly, disable the dnf-automaticfeature.

      # for i in dnf-automatic-download.timer dnf-automatic-install.timer dnf-automatic-notifyonly.timer dnf-automatic.timer ; do systemctl disable --now $i; done

# dnf remove dnf-automatic
