docker run flashfocus

not sure if correct, I haven't used docker much

Grr arch's gpg keys have caused no end of trouble with this dockerfile. Thanks for the fix @Artturin. Confirmed that the build is working on my end as well. Was that test failure run from this branch? I just ran the tests from this branch and all seemed to pass:

make run_tests
...
============================================ 122 passed in 21.13s ============================================

I'm happy to merge this unless there's anything more you wanted to look into re: the test failures?

[Artturin]

i ran it from this branch, perhaps there's something that only works on your system. will investigate more

this can be merged

(ready to merge)
