解决方法：
docker image prune -a
docker container prune -a
docker system prune
docker system df
There are a few reasons why you encounter these errors:
There might be an issue with the existing cache and/or disc space. In order to fix it you need to clear the APT cache by executing: sudo apt-get clean and sudo apt-get update.
The same goes with existing docker images. Execute: docker image prune -f and docker container prune -f in order to remove unused data and free disc space.
If you don’t care about the security risks, you can try to run the apt-get command with the --allow-unauthenticated or --allow-insecure-repositories flag. According to the docs:
Ignore if packages can’t be authenticated and don’t prompt about it. This can be useful while working with local repositories, but is a huge security risk if data authenticity isn’t ensured in another way by the user itself.
Finally, on MacOS, where Docker runs inside a dedicated VM, you may need to increase the disk available to Docker from the Docker Desktop application (Settings -> Resources -> Advanced -> Disk image size).
