This really looks like a proxy issue. Are you using a private network that requires to set a proxy (e.g. network from an enterprise, from a school, etc.)? If yes, I'd suggest to contact your network admin to know how to setup the proxy correctly (typically with HTTPS_PROXY/HTTP_PROXY env variables)

Hi @Wauplin, thanks for your quick reply. I'm working on a private network and have already tried setting the HTTPS_PROXY/HTTP_PROXY environment variables (I'll double-check them). Could there be any other reasons why this issue is happening?

Not that I can think of no. If you have any way to retry to download from another network just for a test, that can help you assess if the problem really comes from the network or from the laptop/something else.
