[Librem-5-dev] queries with dev kit environment set up

Sat May 25 16:18:23 PDT 2019

Hi Dan,

as I said, the root login in the documentation is a mistake; I actually thought it was long gone, together with the IP address.

It also seems you got a dev kit that was flashed with a different version of the image than the tutorial is making use of.

If the /etc/ssh/ssh_host* files are empty, I recommend reflashing, or following what I wrote in the previous email. But really, reflashing is a good idea anyway. Sorry for the trouble!

Cheers,
Dorota
