I'm using jaunty i386 and I started to experience the same issue. Everything was ok then I generated a keypair using ssh-keygen with a non-empty passphrase. I copied it to my target machine's .ssh/authorized_keys file and ssh command was able to log in (the passphrase was asked in a window dialog).
After sometime I decided not to use a passphrase anymore. So I used ssh- keygen with empty passphrase. This new key pair and all the subsequent ones I created (with empty passphare or not) did not work, reporting `Agent admitted failure to sign using the key', without even asking for a passphrase. After reboot, I didn't see the problem. Repeating the process (setting up new key pairs), I happens again. Then I found out a way to fix it without rebooting: 1. remove the key pair files from ~/.ssh directory. 2. ssh the remote machine (this is step is needed). Don't need to login, just wait for the password prompt. 3. generate a new key pair. After setting the public key in the remote site, the problem goes away. It seams that seahorse does not like the key pair being modified externaly. I am able to provide any more information as needed. -- 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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
