Following today's announcement of patches for the Microarchitectural
Data Sampling (MDS) vulnerabilities, I ran updates on my two Hyperbola
VMs.  One updated without problems, but the other one consistently
gets signing key errors for one particular key.  I tried key refreshing,
without effect.

I then tried the drastic solution of destroy the key directory and
recreate it with

	rm -rf /etc/pacman.d/gnupg
	pacman-key --init
	pacman-key --populate archlinux
	pacman-key --populate parabola
	pacman-key --populate hyperbola
	pacman-key --refresh-keys

I still get the same error, which looks like this:

	# pacman -Sy hyperbola-keyring

If I invert any of the response (yes <--> no), pacman terminates

Does any list member have an idea how to repair this blockage? I have
more than 100 packages in need of updates.
