I'm running 16.04 and attempting to use the builtin Backup program which is a wrapper around deja-dup. I'm trying to target an SSH server for backups, as it will use rsync block comparisons and be the most efficient. However, the SSH server has disabled RSA public key authentication and only supports ecdsa and ed25519.
Backup is using gnome-keyring by default, so it refuses to connect to SSH. From /var/log/auth.log: May 23 15:10:42 hollywood gnome-keyring-daemon[1599]: Unsupported or unknown SSH key algorithm: ssh-ed25519 Thus, this bug is making other builtin tools less useful as well. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-keyring in Ubuntu. https://bugs.launchpad.net/bugs/771272 Title: gnome-keyring doesn't support ecdsa or ed25519 keys Status in GNOME Keyring: Confirmed Status in gnome-keyring package in Ubuntu: Triaged Status in gnome-keyring package in Debian: Confirmed Bug description: Binary package hint: gnome-keyring I'm not sure I have described it correctly in the summary, but this is what happens: I run ssh-add in a new terminal and enter my passphrase, which is the same for my DSA and ECDSA key: the DSA identity is added, but the ECDSA gets the "Error reading response length from authentication socket.
