Docker Pull Error: 'cnetos' Access Denied & Runtime Error: Invalid Memory Address

This error message is returned by the Docker engine. It indicates that the Docker engine could not pull an image named 'cnetos'. This could be due to one of the following reasons:

• The image 'cnetos' does not exist.
• You need to log in to Docker before pulling the image.

The error message also mentions a runtime error, specifically an invalid memory address or nil pointer dereference. This indicates a potential issue within the code logic or memory management, likely requiring further debugging and analysis to pinpoint the exact cause.
