Note that on my system, it doesn't like any extra content, so it needs to be:
[testenv:lint]
commands = flake8 src/ tests/
deps =
    flake8==3.7.9

With
[testenv:lint]
commands = flake8 src/ tests/
deps =
    flake8==3.7.9 # to match focal

it still fails

I've tested this in a bionic LXC as well as on focal, fwiw.
