I am facing the below issue when I do:
oc import-image php --from quay.io/${RHT_OCP4_QUAY_USER}/php-73-ubi8 --confirm
import failed: internal error occured: missing signature key
This is a known issue and there's a work around for it. You can reference the thread https://learn.redhat.com/t5/Containers-DevOps-OpenShift/DO288-lab2-ch2s07/m-p/22088
Hope that helps
I had to use skopeo with format v2s1
