Restore failed for bad destination password

[DavidePrincipi]

If the backup destination encryption key does not match the Restic repository an error occurs. The error is difficult to understand for the end user.

For example:

restic --option=rclone.program=/usr/local/bin/rclone-wrapper snapshots --json
Fatal: wrong password or no key found
Traceback (most recent call last):

    pret = agent.run_restic(rdb, repository, path, ["--workdir=/srv"], ["snapshots", "--json"], text=True, encoding='utf-8', stdout=subprocess.PIPE, check=True)
