Hi, I’m trying to run an elixir script on an Ubuntu 16.04 server (yes, I know it’s old, but we run the same script on other servers and it works ok :wink: ).

I installed erlang and elixir using asdf:

These are the versions installed:

.asdf/installs/elixir/1.18.3-otp-27
.asdf/installs/erlang/27.3

Now, when I try to run my script I get:

P.S.: I’ve read and tried everything at Unable to run mix local.hex and mix local.rebar, but the problem persist.

Any hint?
