[aguxez]

Getting the exact same error.

[chichocom]

The problem is in the repository (@edge) in dockerfile.build.. This only has the latest version of elixir that today is 1.4.4.
Solutions:

• Modify the elixir version to 1.4.4 in dockerfile.build.
• Change the repository to one that has more elixir versions.

Modifying the elixir version in Dockerfile.build to 1.4.4 fixed the problem. Thanks!
