You need to tweak /etc/ssh/sshd_config to allow root to connect through ssh (PermitRooLogin yes, maybe add it in the AllowUsers also). Then connect back as root.
Edit : don’t forget to reload the ssh daemon after that (service sshd reload)
Is that a new behaviour in 2.5 ?
When I installed my 2.4, root connection was allowed by default (and I remember that some people advised me to change this behaviour)
That’s a good thing for security, but as @Tuxicoman said the way to change it should be indicated in the doc.
Because it’s important to know the default behaviour (some people might want to finish the install via SSH and will be blocked) and how to change it.
Thanks !
Yes, we should definitely add it in the doc (feel free to open a pull request for that).
I just want to add that the recommended way to install is using the Yunohost image, given that starting from Raspian is tricky (because ssh is not enabled by default, and so on). We might want to add a “recommended” next to the title to clarify that as well.
