Error during restoring registry backup

While restoring a backup of a registry (as part of a complete restore), we get the trace below (the backup is from 1 server and the restore is on a local vm, the secrets file is copied and we did run a reconfigure)

Version 10.0.3

It reports something about a move of the registry dir failing:

** Invoke gitlab:backup:registry:restore (first_time)
** Invoke environment
** Execute gitlab:backup:registry:restore
