Re: Openshift disconnected mirror registry failure

@LuisGonzalez  thanks for the feedback, 

i followed the skopeo procedure, still the same. I face the same issue for 4.7.7 

am I missing any pre-requisite/steps? 

I followed the procedure in 

https://docs.openshift.com/container-platform/4.7/installing/installing-mirroring-installation-image...

[root@registry ocp]# GODEBUG=x509ignoreCN=0 skopeo inspect --authfile /root/ocp/pull-secret docker://registry.ocp4.example.com:5000/ocp-release/openshift4:4.7.32
FATA[0000] Error parsing image name "docker://registry.ocp4.example.com:5000/ocp-release/openshift4:4.7.32": Error reading manifest 4.7.32 in registry.ocp4.example.com:5000/ocp-release/openshift4: manifest unknown: manifest unknown
