No output from "restic list snapshots", "restic stats" etc. for S3 backend

[perry-mitchell]

Describe the bug I'm using autorestic to backup a local mount to an S3 backend (Scaleway, not AWS). After some testing (where check wouldn't work) I managed to get check to initialise a repo on the remote S3, and allowed a couple of backups to run. Some files are transferred and I can see the encrypted content in the S3 bucket.

When I run some restic commands (via autorestic) on the backend, however, I get no output:

$ autorestic exec -b <snip> stats
Using config: 	 /home/<snip>/Temp/s3_autorestic/.autorestic.yml
Using lock:	 /home/<snip>/Temp/s3_autorestic/.autorestic.lock.yml


    Executing on "<snip>"    

$

$ autorestic exec -b <snip> list snapshots
Using config: 	 /home/<snip>/Temp/s3_autorestic/.autorestic.yml
Using lock:	 /home/<snip>/Temp/s3_autorestic/.autorestic.lock.yml


    Executing on "<snip>"    

$

Check is OK:

$ autorestic check
Using config: 	 /home/<snip>/Temp/s3_autorestic/.autorestic.yml
Using lock:	 /home/<snip>/Temp/s3_autorestic/.autorestic.lock.yml
Everything is fine.
