Hi,

I triesd to make a local hex repo based on the docs here: Self-hosting | Hex and i run into a problem. Certain tar files downloaded from the official hex repo are not working with my local repo.

Here’s a bash script that reproduces the error:

#!/bin/bash -x
DIR=try
rm -rf $DIR
mkdir -p $DIR/tarballs
mix hex.package fetch hackney 1.4.2
cp hackney-1.4.2.tar $DIR/tarballs/
openssl genrsa -out /tmp/private_key.pem
mix hex.registry build $DIR --name=test --private-key=/tmp/private_key.pem 
mix --version

Here’s it’s output:

+ DIR=try
+ rm -rf try
+ mkdir -p try/tarballs
+ mix hex.package fetch hackney 1.4.2
hackney v1.4.2 downloaded to /home/otp00300830/hackney-1.4.2.tar
+ cp hackney-1.4.2.tar try/tarballs/
+ openssl genrsa -out /tmp/private_key.pem

What goes wrong here?
