It’s hanging on the keyring step because pacman-key is waiting for enough entropy, and UTM VMs can be pretty bad about providing it.
Before you run the install again, add a random-number device to the VM:
Shut the VM down completely.
Open the VM settings in UTM.
Go to the QEMU section, then Additional Arguments.
Add:
-device virtio-rng-pci
Save it and boot the installer again.
That gives the VM a proper source of randomness from the host, so the “Generating pacman master key” / “Updating trust database” part should finish quickly instead of sitting there forever.
If you can’t add that argument for some reason, there’s a crude workaround. When it hits that step, click inside the VM and move the mouse around and hammer random keys for 30–60 seconds. That can help feed the entropy pool enough to get it moving.
The RNG device is the proper fix though. Once that’s in place, you shouldn’t hit this again.
Give it another shot and let me know what happens. This happened to someone else once, and I thought I had it fixed
