I use it daily, before turning off password authentication make sure you can use the key login first
copy ssh keys via
ssh-copy-id root@<ip-address>Of course ssh-copy-id will prompt for a password as it isn't able to connect because no keys are present.
On my systems /storage is owned by root:root
lol, probably you didn't understand. It copy the keys but didn't work.
Thank linux god, systemctl is working and I found the issue. For some reason (which I believe is a bug) the /storage was owned by user 1000 (never exist) plus the permissions where 755 instead of 700 (since it is considering root home directory).
Anyway logging should be better (at least it should be on tmpfs/ramfs)
There is no way that that can happen without user input

I can confirm this bug: owner of /storage was id 1000 and the permission was 755. After fix owner and permission ssh without password works perfectly
Copying the keys won't do a darn thing if you don't have a key agent running on the server you're coming from. Are those set up as well?

I can confirm also. New libreelec installed from noob, and just updated to 7.0.3. The /storage is being set as a "normal user", which doesn't exist, by the installation. Fix with: chown root:root /storage ; chmod 0700 /storage

Nope. That's how some installation come -- probably isn't seen because so few people use ssh & set their keys & fight with it after the fail.
