GNOME Bugzilla – Bug 756398
No longer sets SSH_AUTH_SOCK
Last modified: 2015-10-16 20:36:11 UTC
As of version 3.18, gnome-keyring no longer sets SSH_AUTH_SOCK making it essentially dysfunctional. I am observing this on Arch Linux, it has also been reported for Fedora.
This was due to the way that gnome-keyring's new GDBus support affected startup. Should be fixed in bug #756059 *** This bug has been marked as a duplicate of bug 756059 ***
