my problem is, that I do not have screen and keyboard on raspberry. And I am trying to connect to it via SSH. But from default is in sshd_config set: PubkeyAuthentication to yes. And that is my problem, because when I copy .img file to SD card I`m unable to login via ssh because of pubkeyauthentication. How can I change it to no using my PC? (Ubuntu) I tried to mount .img file and edit sshd_config, but I am able to mount it only read-only. What do u suggest?
