Unable to restore omnibus backups

Summary
I create a backup using mmomni backup -o /backup/20230313.tgz without error.
When I try to restore the backup using mmomni restore /backup/20230313.tgz, I get errors.

Steps to reproduce
On 7.8. Create backup. Restore backup on a new installation.

Expected behavior
Was expecting the restore to work, being able to then continue with a mmomni reconfigure.

Observed behavior
The error messages I get are:
ubuntu@:/backups$ sudo mmomni restore 20230313.tgz

Backup extracted into temporal directory “/tmp/mmomni_714919275”

Configuration restored in “/etc/mattermost/mmomni.yml”
