flake8 currently incompatible with pyflakes in edge
py3-flake8 is currently broken in edge, because it depends on a specific version of py3-pyflakes, and pyflakes was updated.
pkg_resources.DistributionNotFound: The 'pyflakes<2.2.0,>=2.1.0' distribution was not found and is required by flake8
I'll prepare patches to fix this, first by applying https://gitlab.com/pycqa/flake8/-/merge_requests/417 to flake8, so it works with the newest pyflakes version. This is an unmerged patch, but the latest release of flake8 is still not compatible with pyflakes. To make sure we don't run into this in the future I'll add a note to the pyflakes aport that it should only be upgraded together with flake8 in alpine.
