[Bug 328277] Re: can not login using ssh anymore
I am also affected. Seems to be a problem with gnome-keyring or similar as the problem does not occur from the console. The steps listed above by Christian also resolved it temporarily for me. Removing the .ssh directory also does it.

I am affected, too, cannot ssh to anywhere from gnome session. The problem is apparently in gnome-keyring-daemon that has been recently updated. ssh does work if I break its connection with the agent: SSH_AUTH_SOCK= ssh localhost Enter passphrase for key '/home/crosser/.ssh/id_rsa': Linux pccross 2.6.28-7-generic #20-Ubuntu SMP Mon Feb 9 15:42:34 UTC 2009 x86_64 In case it helps somebody, I am attaching strace of the gnome-keyring- daemon when it ssh command is issued.
