Last active September 7, 2018 08:54
Disable Gnome Keyring SSH agent in (X)Ubuntu
# Disable Gnome Keyring SSH agent in Ubuntu
# To allow using ssh-agent from OpenSSH, mainly because
# gnome-keyring does not like EC-type SSH keys
# as regular user (for which to disable):
systemctl --user mask gnome-keyring-ssh.service
pam-auth-update
# and disable "GNOME Keyring Daemon..."
# which probably also disables automatic keyring unlocking on login
