I'm trying to use duplicity to backup a directory to DropBox in Debian Stretch. However, duplicity gives me the error:

UnsupportedBackendScheme: scheme not supported in url: dpbx:///

I have verified that /usr/lib/python2.7/dist-packages/duplicity/backends/dpbxbackend.py and /usr/lib/python2.7/dist-packages/duplicity/backends/dpbxbackend.pyc exist so I don't know what the problem is. Could anybody please guide me?

The command I run is:

duplicity full ~/alfresco/ dpbx:///

I was running the same issue using duplicity 0.7.18.2 in Ubuntu 16.04 and I solved it by reinstalling python-openssl:

  1. sudo apt purge python-openssl
  2. pip install pyopenssl

make sure to have the dropbox python library installed, It seems that duplicity is just trying to import the backend plugin, and it is failing with ImportError: dropbox or something, and that results in the UnsupportedBackendScheme error

this should work:

pip2.7 install dropbox
