Hi, As per this: https://qa.debian.org/excuses.php?experimental=1&package=python-jsonschema
version 4.19 introduces regressions in at least 5 packages... Patches to fix these are warmly welcome.
Also, I'm not sure why this same page reports that the package is "uninstallable on arch arm64"...
Cheers, Thomas Goirand (zigo)
