I believe this is a dbus issue, and it went away when I increased the number of connections allowed by dbus. To do this, create the file /etc/dbus-1/system-local.conf and add to it:
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig> <limit name="max_connections_per_user">256</limit> </busconfig> Save and restart. -- Unlock button throws an error, doesn't authenticate https://bugs.launchpad.net/bugs/187335 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
