Hi,

For several days I have been having problems trying to run livebook.

I have installed Erlang and Elixir using asdf.

The Erlang version I am using is 24.0.2.
The Elixir version I am using is 1.21.1-otp-24.

I am using Ubuntu 20.10 groovy (x86-64), Linux kernel 5.8.0-55-generic.
live.

I run

git clone GitHub - livebook-dev/livebook: Automate code & data workflows with interactive Elixir notebooks
cd livebook
mix deps.get --only prod

And that’s what appears:

Could not find Hex, which is needed to build dependency :phoenix
Shall I install Hex? (if running non-interactively, use “mix local.hex --force”) [Yn]

I press Y and enter. The error message is below:

12:32:52.202 [error] Task #PID<0.109.0> started from #PID<0.94.0> terminating

Could someone help me?

This typically means your Erlang was installed without a linked openssl or similar library. So you need to address that first. In this case, perhaps the quickest way to run Livebook is using the Docker image?

Thanks, José.
It was already working with Docker.
The problem had nothing to do with Erlang, Elixir or Livebook.
I have found a very simple solution after hours and hours trying to fix my Ubuntu.
I have just created a new user, installed asdf again. Then I installed Erlang and Elixir (the versions above) and ran livebook with “MIX_ENV=prod mix phx.server”. Everything works now.
