Issue

[DEPRECATION NOTICE] registry v2 schema1 support will be removed in an upcoming release. Please contact admins of the docker-registry.qualcomm.com registry NOW to avoid future disruption.

This is an official statement of Docker from Feature Deprecation Policy. Related to "[DEPRECATION NOTICE] registry v2 schema1 support will be removed", you can check that the desired version would be v19.09.0:

Pushing and pulling with image manifest v2 schema 1
- Deprecated in Release: v19.03.0
- Target For Removal In Release: v19.09.0
Check the information: https://docs.docker.com/engine/deprecated/

That means that the image manifest v2 schema 1 format is deprecated in favor of the v2 schema 2 format. If the registry you are using still supports v2 schema 1, it needs to be moved to v2 schema 2. Red Hat Quay v3 and onwards supports manifest v2.
