Installation fails on Ubuntu 16.04

Changing the base image of the Dockerfile to ubuntu:xenial (Ubuntu 16.04) leads to three tests failing (Makefile:170: recipe for target 'run-test' failed). Compilation itself works normally.

The build passes on trusty and precise distributions. It might be an issue with Docker. Could you post more details about the error message? I'll see if it works on xenial on travis and I'll get back to you.

I can confirm the issue on xenial. The code compiles, but three tests fail.
