Followed the Windows install instructions but am not able to get Hex installed.

I do not have this issue on my main Ubuntu machine but only within the Windows 10 virtual machine.

Mix requires the Hex package manager to fetch dependencies
Shall I install Hex? (if running non-interactively, use "mix local.hex --force") [Yn]

Alternatively, you can compile and install Hex directly with this command:                                                                                                                                                                          $ mix archive.install github hexpm/hex branch latest

Versions:

A quick fix might be to run mix hex.config unsafe_https true

I ended up running mix archive.install github hexpm/hex branch latest which worked.

Nevermind, broken again…

> mix deps.get
...
telemetry_metrics 0.6.1
telemetry_poller 1.0.0
websock 0.5.3
websock_adapter 0.5.4

Could not install Rebar because Mix could not download metadata at https://builds.hex.pm/installs/rebar3-1.x.csv.

mix hex.config unsafe_https true did not resolve the problem but thanks for the suggestion.

Try this?

apt install ca-certificates
