Environment:
Host OS: Mac OS Catalina Docker Version: Docker version 19.03.8, build afacb8b
Problem:
From inside docker, I have ensured I can ping 8.8.8.8 and also resolve hostnames. But I dont understand why I am seeing ***
unexpected size error
when I run apt update.
From bash terminal, I run the following commands:
docker run -it ubuntu:18.04 bash
