0.8 series : can't get duplicity to run : UnicodeDecodeError

[Sébastien Stoquert]

Hello,

I'm running Ubuntu 18.04.1 LTS and duplicity from the repository from today (05/01/19) and the following error occurs when running any command with duplicity.
I followed the instructions of https://docs.ovh.com/gb/en/storage/pca/duplicity/, in order to enable pca backend on my ubuntu machine.

I tried to purge and re-install python, duplicity and all requirements without success.
The duplicity 0.7.17 works fine on my computer (tried with sftp).

Thank you for your time and answers
