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
