Hey,

I have a NanoPi-M3 and try to install Elixir on their Ubuntu image. I followed the Raspberry Pi installation instructions from the Elixir website and installed Elixir 1.6.

pi@NanoPi-M3:~$ elixir -v
Erlang/OTP 20 [erts-9.1.5] [source] [smp:8:8] [ds:8:8:10] [async-threads:10] [hipe] [kernel-poll:false]

Elixir 1.6.1 (compiled with OTP 19)

Now when I try to install Hex I get:

pi@NanoPi-M3:~$ mix local.hex

18:04:10.362 [error] Unable to load crypto library. Failed with error:
":load_failed, Failed to load NIF library /usr/lib/erlang/lib/crypto-4.1/priv/lib/crypto: 'libcrypto.so.1.1: cannot open shared object file: No such file or directory'"
OpenSSL might not be installed on this system.

Could not install Hex because Mix could not download metadata at https://repo.hex.pm/installs/hex-1.x.csv.

I then tried to install erlang-crypto but it fails due to missing libssl1.1.0.

pi@NanoPi-M3:~$ sudo apt-get install erlang-crypto

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 erlang-crypto : Depends: libssl1.1 (>= 1.1.0) but it is not installable
E: Unable to correct problems, you have held broken packages.

Then I compiled OpenSSL 1.1.0 from source.

pi@NanoPi-M3:~$ openssl version
OpenSSL 1.1.0f  25 May 2017

But I get the same error when I try to install erlang-crypto.

Now I am at the point where I want to throw the NanoPi-M3 into a corner of my room. It’s really frustrating that it seems to be impossible to get anything working on an ARM based machine.
