Hi,
I am trying to run x2go with a macOS Mojave client and a Ubuntu 18.04 server. When trying to connect, I keep getting the following error: "Access denied. Authentication that can continue: publickey,password". It seems like this is an error other people had before, so I tried multiple things that were suggested on various feeds, but nothing helped. I tried logging in with a different user, changed the user passwords, changed the passkey of my private key, I tried all combinations of the "PasswordAuthentication","ChallengeResponseAuthentication" and "PubkeyAuthentication" settings in my sshd_config file. I checked whether the correct key is in the authorized_keys file, I checked that the .ssh directory and the authorized_key have the correct permissions. I restarted multiple times and tried changing the presettings of my connection, e.g. I tried not entering the directory for my private key, which gives me an additional error saying: "Failed to read private key:/Users/Franziska/.ssh/id_rsa". Using a normal OpenSSH client and logging on to the server via the command line works fine. I don't really know what more to try so I would be very grateful for any kind of help!
Thank you very much in advance!
Kind regards, Franziska Goltz
