Bug Description
when using the WebDAV backend for a provider with a long password, the following error is generated:
Attempt <x> failed. ValueError: Invalid header value 'Basic <base64>'
This problem appears to stem from the fact that the base64 value of the username:password pair contains newlines when the pair is of sufficient length. Please see the attached patch for my proposed solution. I have found this issue and the solution on a CentOS machine with duplicity from EPEL, however based on the source code viewable via launchpad I believe the issue is still present in the latest source, and I believe the patch can also still be applied.
After applying the patch, the WebDAV backend works successfully for my providers (TransIP Stack and pCloud), however that is also the only verification I have performed.
Duplicity version: 0.7.17
Python version: 2.7.5
OS Distro and version: CentOS Linux release 7.4.1708 (Core)
Type of target filesystem: ext4 (local), WebDAV (remote)
Log output from -v9 option: Did not capture this, in case it is necessary, please ask and I will revert the patch to capture it.
