Comment 13 for bug 1086374

I got this error when attempting to list files with 0.7.18.2.

The root cause in my case was a bad path in an "sftp://" URL. It was important that the absolute path after the host name started with two slashes, and that the URL point to a folder that contains "duplicity-full..."files. My correct URL also ended in a slash.

It's a scary error message and it should give you a hint if the folder is wrong or there's really some other problems. For example, one message could say "No duplicity files found at the provided URL. Confirm the path to your backup folder is correct."
