Spent a good hour last night trying to get passwordless SSH working with
my new zero W.
Managed to set the /boot/ssh file and get wifi running by editing the SD
image for a headless setup, but SSHd flat out refuses to accept my
key pair for authentication. Password authentication works fine.
I’m using a DSA key which works with every linux server I’ve ever tried,
but the setup on the latest raspbian will not accept it. It doesn’t see it
as a valid protocol? (NB I am 100% sure this is not the usual permissions thing)?
Am I missing something obvious, or do I have to use RSA keys?
