The following commands from Fernado in the above link fixed the problem.
sudo pacman -Sw ca-certificates-utils
sudo pacman -U /var/cache/pacman/pkg/ca-certificates-utils-20210603-1-any.pkg.tar.xz
sudo pacman -Syu
Thank you to @dalto and @pycrk. Evidently it is the ca-certificates-utils that actually installs the certificates?
I need an ARM 32 Bit OS to compile things for the armv7h EnOS repository. Yesterday I had to compile yay and my current RPi 4b 32 Bit OS was Cinnamon. It once again came up after login and said it was in the fall back mode, which is useless. I spent too much time getting it to work to compile one package. So today, I installed 32 Bit KDE the “Arch way”. Command by command. Fortunately @dalto 's eos-packagelist made the process a lot speedier.
