I have been trying to setup passwordless SSH for a Backuppc system. I have three Debian 10 systems (including the server) . SSH sets up fine on one of the client machine and "ssh backu...@192.168.254.xx starts without asking for a password. The other machine (supposedly identical) not only asks for a password but will not accept any of the known passwords. If I go to the offending machine and attempt to su to the backuppc user , I am asked for a password and no passwords work. This doesn't allow the use of ssh-copy-id for transfering the encryption key to that machine. I have tried to reset the backuppc password three times but did not solve the problem. In both systems the public key is stored in /var/lib/backuppc/.ssh as id_rsa.pub.
I also have a Windoz 7 laptop that I want to include and have managed to get ssh and rsync installed (what a mess that was). I have not tried to get passwordless access to that yet. For later.
Any insights? Gary R.
