Issue with easy_ssl.ex

[Cyb0rg42]

I trying to run certstream-server and got the following error:

root@vrfcanalyzer:/usr/src/certstream-server# mix run --no-halt
warning: use Mix.Config is deprecated. Use the Config module instead

Running Ubuntu Server 20.04.6 LTS (Focal Fossa) fully patched.
mix deps.compile easy_ssl --force doesn't fix the error. Same error message as above
Any idea what is wrong?

you may need to install erlang-dev - apt-get install erlang-dev

dpkg -L erlang-dev | grep OTP
/usr/lib/erlang/lib/public_key-1.7.1/include/OTP-PUB-KEY.hrl

dpkg -L erlang-dev | grep OTP

Already didn't fix the issue.

Could you give it a try with the Ubuntu managed packages ? it seems you're installing from a rabbitmq PPA
So it may be an erlang version mixup or the rabbitmq ppa packages this differently

update: I can reproduce with add-apt-repository ppa:rabbitmq/rabbitmq-erlang in a ubuntu:20.04 docker container - using Ubuntu packaged elixir and erlang-dev everything compiles fine. Probably the Ubuntu packaged elixir (1.15.7) can't run against erlang 26 provided by the rabbitmq PPA

You may need to run this in docker or use something like asdf to manage multiple versions of erlang (I have zero experience with asdf)

Thanks. Removed all erlang packages from rabbitmq and installed erlang from the Ubuntu repo
BTW:
I followed the instructions on https://elixir-lang.org/install.html
A link to this page can be found at: https://github.com/CaliDog/certstream-server?tab=readme-ov-file -> "instructions for your platform"

Debian (and Ubuntu) alternative

Use the [RabbitMQ Packages](https://launchpad.net/~rabbitmq) (might not be up-to-date however likely newer than the distribution)

$ sudo add-apt-repository ppa:rabbitmq/rabbitmq-erlang
$ sudo apt update
$ sudo apt install elixir erlang-dev erlang-xmerl

ws:// vs wss:// like http:// vs https://

you probably have no SSL/TLS configured on this localhost:4000 websocket endpoint, try the same using ws://localhost:4000

update: answering a deleted question by OP

This pull request fixes the issue:
CaliDog/EasySSL#17

You can test by manually editing deps/easy_ssl/mix.exs and adding :public_key to extra_applications.

extra_applications: [:logger, :public_key]

For all future MacOS users (and maybe users from other platforms) - the issue probably stems with using the latest Elixir. Going into mix.exs and changing the EasySSL dependency to: {:easy_ssl, github: "CaliDog/EasySSL", branch: "master"} worked!
