Bug 1906585

An unexpected error occurred while creating the scratch build and has been automatically reported. Sorry!

This is needed for python-diff-cover... see bug 1923076

OTOH two packages will get broken:

python-requests: (python3dist(chardet) < 4 with python3dist(chardet) >= 3.0.2)
python-aiohttp: (python3.9dist(chardet) < 4 with python3.9dist(chardet) >= 2)


I'd rather not break requests and aiohttp for diff-cover. Let's revert the diff-cover update if this is urgent. If not, we can check with upstreams wrt chardet 4 compatibility.

aiohttp should be fine: https://github.com/aio-libs/aiohttp/commit/b0ed732d0a637e43c72bb1a777d02776cde37376

requests as well: https://github.com/psf/requests/commit/516f84f490ccd352672847c6a3d23c67a13b3f98

Sie note:

Please even if we update chardet, revert the --no-discard-stderr argument to help2man. It hides the failure:

With --no-discard-stderr, you basically embed the error to the man page instead of seeing it. I've been bit by this previously as well, the error is hidden by default, but the flag does not show it, it converts it to the manpage content :/
