[Duplicity-talk] SCP Issue With duplicity 0.7.01 and rsync.net

[Simon Watson]

Hi,

Just letting you know I came across an issue with using duplicity 0.7.01 and my rsync.net account.

When I used duplicity 0.7.01 with the scp protocol to connect to my rsync.net account it would fail with:
BackendException: scp mkdir failed(2): test: target/remote/directory: unexpected operator

Thanks to Kenneth Loafman's assistance I was able to resolve this issue.

If I changed to using the sftp protocol instead it would work fine. Also if I downgraded to duplicity 0.7.0 or lower it would also work fine. So it seems like a remote command that duplicity 0.7.01 uses with the scp method won't work on rsync.net accounts.

Is anyone else able to replicate or confirm this issue?

Here is the full traceback for the exception I was getting:
