I need to update the master password for the Gnome keyring.
The Gnome instructions refer to a GUI menu for this.
The reasons are a little complicated, but I can’t see this menu, because I am using the Qubes operating system - we just don’t have it as a GUI.
I need a way to launch this menu, or a terminal command, that will let me change the master password.
(As far as I can tell, the command gnome-keyring isn’t enough for the job - but I am happy to be proven wrong.)
