Error: Authentication information is not set

[crpb]

Hello,

i just gave this a try and after running make in the local clone i immediately ran into this problem.
(Well, after another one in an Include'd configuration where i had a line Match Host="list,of,ips,and,hostnames" which i changed to Match Host "list,of,ips,and,hostnames" which fixed that).

Anyhow, here the output and some information that might be useful 🤔

So as you can see ssh localhost works just fine.
