I am experiencing the same issue by generating the private rsa key from seahorse and from inside the cli as well.
Seahorse and ssh-copy-id both copy the key to the remote user, but every time I try to connect, the error message gets shown. No errors get logged inside my home/.xsession-errors, nor in /var/log/auth.log Here follow my two keys: -----BEGIN RSA PRIVATE KEY----- MIIEowIBAAKCAQEArOElXA9OgEITnk43htSTVA4MKCq3fgx+IbciDhy9RIdYP62H qWV6+X3UOQEP0QTMP+mDvs2p88WrJ+ukNCAA41qxbJb8j199GsGp3o8InjOh6yCp Gmwg5DKynRrRv2ZIv4zlPx+ZxZx9WAskT50Tu7Op2QW3MKLCLNdB3XGevOjUhniM wkEI4GxA/BI9dOiM097GjmzAffB103NsIxknfvgNaZ5oI5Z6PHej/QYDxn2MAQ3i 4IEST791YssFIq6bH4oWiwMvqIySPBM2xAf8HOvxphZ4UtkiV0WrFXoNJvumPnUA QNd+pvZ/W+iSW+38/0jeD/uVPmdlg4GPysUNNwIBIwKCAQEAmR8vt/BM2AACv2nZ aMro5AxxKuQBm4doZwFKDH/a1kv9tL5E9R9eSrFG8KkrRBoxP+wVml5jVEFdFLrE ozJJ7fE+D7juUxoPuJzm6bHjD8dU5jLe64RXpYv9SVJEv3faCL6fKUff+CuE9jXB E1CccwzYQ+B9rrwLEcX4gk6xKvimM90r6wP4kEiZ9PIpj3bee3epDCQfgIYxDTpV +mbAg0XtIcjK9PUQYD6XQx7oHzxROAdy3F9xrhN5DhJx1Kj5xadyR9eIy5nVZQf1 RXCScG51Qz/l76+7Ma/oh144liaDkPYu0Br/HmiyOwE+IOELbO/TQc3nFMzUz1Y9 c/qBIwKBgQDdD4VtIS8nku1Harc59Ay0E+NdfJQb5mghscJLkiqW7XLpiWaAEulz FAsGSjiw/zjfKHLre35u8slE+q1i61/sQcoaoMi4Bb8sd5AYPQ3TFp1TbbG+Kw0V gOv2LglW/mEf3X7lurpJ5K7LNKH4piklNWjT9zeRNB863Abe+LMEIwKBgQDINCK0 POQbPz2FjVHc1p/2VZ2ZsY7TmxHar6kSEx+3Nx1quhMj89poSCXy6yZMtIS0PoIK W6+nJM+v/WOl05gpgrib67J6F8TgMWmeQNXmyW7PgRyVhInF4FEJNdTI2erplAEv /kDKZiQUNzzwd9+I0wLRQhVZ+w5TKL579EnJ3QKBgQCRRLbEDn4SsQJTgKRKp7CT mApwolKzP6OD2zaJbq5F7H62uWCdTkGjZPFNRreKQVFCMIYIdbl8G+NZNwQ5sJ4e 6WeN119UW4xByumphzT4bfJbZVeLmKIys85CsInLc/auij1yZMOPpOfknu4YbTD7 MbnqYKDbwyp3It/xnB3eJQKBgQCDj/mMYodFGu3qDGj+1i6akAh68QYWBtE378bf /fBFMtjRGzEmQSkf9OW846t0PByw9eBtNO/Fm9jv/kjMDrRzDMJ1FzrFQtHVJ8kQ OTwbUSuPrJ3BVxi1O6L3bISD/OrUAiyqgoJZHoy809eWtSx+fAkqbUE7IVKOaztY xRqL9wKBgEbILKNU+y5S2FBVeuEe58zXiCt00/DQXVIKc/W2V74pFrXwHFAe6n5e 2pvSjUCw+ybJHs433mz1a98WaeTKl42kj3J4QilCa9TZA59DJAgXN5x5ExAaZScC p4h8yY4ULixqe1h++hbFY924i2RjP9+DFdb9S6JXt04GrSV8DRwf -----END RSA PRIVATE KEY----- ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEArOElXA9OgEITnk43htSTVA4MKCq3fgx+IbciDhy9RIdYP62HqWV6+X3UOQEP0QTMP+mDvs2p88WrJ+ukNCAA41qxbJb8j199GsGp3o8InjOh6yCpGmwg5DKynRrRv2ZIv4zlPx+ZxZx9WAskT50Tu7Op2QW3MKLCLNdB3XGevOjUhniMwkEI4GxA/BI9dOiM097GjmzAffB103NsIxknfvgNaZ5oI5Z6PHej/QYDxn2MAQ3i4IEST791YssFIq6bH4oWiwMvqIySPBM2xAf8HOvxphZ4UtkiV0WrFXoNJvumPnUAQNd+pvZ/W+iSW+38/0jeD/uVPmdlg4GPysUNNw== mylocalu...@client to myremoteu...@server client side apps: libryptui0 2.26.1-0ubuntu1 openssh-blacklist 0.4.1 openssh-blacklist-extra 0.4.1 openssh-client 1:5.1p1-5ubuntu1 openssh-server 1:5.1p1-5ubuntu1 seahorse 2.26.1-0ubuntu1 seahorse-plugins 2.26.1-0ubuntu1 ssh-askpass-gnome 1:5.1p1-5ubuntu1 server side apps: libryptui0 2.26.1-0ubuntu1 libgnome-keyring0 2.26.1-0ubuntu1 libpam-gnome-keyring 2.26.1-0ubuntu1 openssh-client 1:5.1p1-5ubuntu1 openssh-server 1:5.1p1-5ubuntu1 seahorse 2.26.1-0ubuntu1 seahorse-plugins 2.26.1-0ubuntu1 ssh 1:5.1p1-5ubuntu1 ssh-askpass-gnome 1:5.1p1-5ubuntu1 -- gnome-keyring-daemon returns Agent admitted failure to sign using the key. https://bugs.launchpad.net/bugs/328127 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
