If anyone else facing this issue. Here is workaround and tracking for your information

As a workaround kindly try the below suggestion.
Add the --format v2s1 flag to the skopeo copy command in the previous step to push the image to Quay with an OCP4.6 compatible manifest.

Refer to https://issues.redhat.com/browse/PROJQUAY-3285 to track the long term fix.

Alternatively, you can build the image by using the podman build --format=docker in step 3.3.

podman build --format=docker --layers=false -t do288-apache ./container-build
