Dear Team, I am trying to upgrade lxc-container from ubuntu 18 to ubuntu 20 and I doing it by destroying and recreating lxc-containers. I have successfully upgraded cinder, glance, heat, horizon,memcached, neutron, nova and placement containers. But now I am unable to create galera, utility containers. I am getting below error for both: failed: [host5_galera_container-ac20] (item={'url': ' http://repo.vexxhost.net/mariadb/key.gpg'}) => {"ansible_loop_var": "key", "attempts": 5, "changed": false, "key": {"url": " http://repo.vexxhost.net/mariadb/key.gpg"}, "msg": "Failed to download key at http://repo.vexxhost.net/mariadb/key.gpg: HTTP Error 404: Not Found"} And it seems the URL http://repo.vexxhost.net/mariadb/key.gpg doesn't exist now. Do we have any workaround for this? Regards, Danish
