gclient runhooks fails to download clang on MacOS because of invalid SSL certificates

[Jonah Ryan-Davis]

Here is the error I see:

Hook 'python3 src/tools/clang/scripts/update.py' took 35.41 secs

I don't know much about this, so I've tried a few things to fix it, none of which have worked:

download_from_google_storage --config

cipd auth-login

goma_auth login

Does anyone have any pointers? I was building just fine last week.

Thanks,

Jonah

There was a non-public thread from a few weeks ago that explained how
to install the missing certs.
