This is the steps we have followed so that we can get our school Raspberry Pi computers to run behind our school proxy without too many issues:
- Configure an apt-cacher NG server to handle your apt-get updates – See this post for more details
- Whitelist the Python PIP domains and use the –proxy:server:port configuration when installing with PIP – See this post for more details
