Hi, thanks for the efforts, but we already have a fix for it ready in PR #1293 (just needs a bit more cleanup before we can merge it in).
The Ubuntu failure itself was due to a breaking change of the Appveyor OS image and has worked before.

Ah - only just spotted this - thank-you.
I'd seen other repos with similar issues, where the issue was related to *nix not liking slashes, or having case sensitive issues around filenames... Sadly I don't have the capacity to run a local appveyor instance to test with, so my tests for this were fire-and-see...
Thanks again
