Problems with Elixir (erlang crypto module) on Ubuntu (ARM)

maybe give asdf a try - I have used that on arm64 servers..

https://github.com/asdf-vm/asdf-erlang#before-asdf-install

https://github.com/asdf-vm/asdf-elixir

I considered it earlier but was unsure if it’ll work on ARM based systems at all.

aptitude is better about unmet dependencies. You can give it a try

sudo apt-get install aptitude
sudo aptitude install erlang-crypto

Of course you do, apt isn’t aware of the source compiled openssl.

When you try to install libssl manually what message do you get then?

It should be available in the Ubuntu arm repositories…

I used @dokuzbir s solution and it worked. But it seems like it swapped the esl-erlang package with the erlang-* packages. I think I gonna do a clean install with asdf later.

I have the same problem but while running a docker-compose run --rm myapp migrate command. Ubuntu 18.04. It fails on this line in my release_tasks.ex:

Ecto.Migrator.run(repo, migrations_path, :up, all: true)

The deployment and migration succeeded many times before so I have no idea why this happened all of a sudden. I even reverted to the last successful deployment and the issue still appeared. I tried @dokuzbir suggestion and it made no difference. I also updated to all the security and os updates. I don’t think I can use asdf because that would obviate the use of Docker. Any suggestions?

here is the pertinent part of the log:

sudo apt-get install erlang-crypto

what kind of error you get when you try install ?

while running as root:

root@****:~/api.faithfulword.app/add-1.2-api# apt-get install erlang-crypto

erlang-crypto is already the newest version (1:20.2.2+dfsg-1ubuntu2).

And how about OpenSSL ? Can you check version of it ?
