mhmm,

======================================================================
ERROR: test_conflicts (test.easyconfigs.easyconfigs.EasyConfigTest)
Check whether any conflicts occur in software dependency graphs.
----------------------------------------------------------------------

I'm not fully convinced that I have conflict there..

@jose-d You're definitely missing download_dep_fail = True (that's automatic for PythonBundle, not for PythonPackage).

The other issue is strange, looking into that...

@jose-d The problem with the failing conflicts test is a bug in framework, it's triggered by merging #7921 which relies on the new multi_deps feature implemented in easybuilders/easybuild-framework#2813, which apparently breaks --check-conflicts

@jose-d Bug is squashed in easybuilders/easybuild-framework#2825, the failing conflicts test should pass after that PR is merged and the tests are re-triggered (@vanzod: please follow up)

Re-trigger Travis after fix

@boegel:
perhaps we're lucky and found another one:

@jose-d "Lucky" indeed... Problem was really fixed in easybuilders/easybuild-framework#2826
