I used the snap backup/restore procedure described [here](https://docs.rocket.chat/installation/manual-installation/ubuntu/snaps#how-do-i-restore-backup-data-to-my-snap). Everything went fine until I tried to restart the server.

Any idea? I confess that I do not understand anything of what’s written here, and looking through internet did not help me much till then.

THX!! 🙂
