Attempting to set up borg, assistance appreciated

More logs:

First Backup in logs, new install attempts: https://paste.yunohost.org/raw/ebekesedat
Second Backup in logs: https://paste.yunohost.org/raw/eziduqabun

It feels like a miracle that the initial installation worked this time without me needing to truncate it. No idea why it told my it was incorrectly formatted before.

I have the same issue with authentication, could someone please tell me what I am doing wrong?

Is it related to this? Surely this would have been patched out in the last 11 months.
