I am seeing this behavior with duplicity 0.7.08 on Ubuntu 16.04.1 LTS. The Backups GUI in System Settings reports that it is running backups successfully and new backup files are being created in the remote location. However, the duplicity command line is unable to run collection-status or list-current-files without error when pointed to the same remote as specified in the System Settings GUI.
