Apt-get update' returned a non-zero code: 100

Hi, I get always the message apt-get -y update’ returned a non-zero code: 100.
After that I get the message
Unable to find image xyz/frameworks-web:latest locally
docker: Error response from daemon: Head “https://xyz/latest

Do you know, what ist the problem?

I feel like you think you shared all relevant details with us…

I am afraid you have to be more specific and provide context information.
