Bug Description


i am trying to push my backups to my seafile cloud which supports webdav.
Duplicity is able to upload the backup but doesn't recognize the existing backup afterwards:
"Last full backup date: none"

Its definetly on the server.

When I use lftp+webdavs instead of just webdavs it can read existing backups but has trouble uploading new ones (so basically the other way around of just webdavs).

With lftp 4.6.3a everything works fine but this version cannot be installed on Ubuntu 18.04.

I'd like just webdavs to work as expected. Any help is appreciated!
duplicity 0.7.17
Ubuntu 18.04

Python3 3.6.5
lftp 4.8.1 (non working as described above)

Have you tried lftp 4.8.1-1 from Bionic? How does it fail?

If you list the webdav directory, do the filenames appear correct? Compare the filenames in the cache to the ones in webdav. Any syntax changes?
