Builds on RHEL 8.2 systems are failing due to this issue. See [1] as to why this is necessary. I used the following command to identify files that need this fix: find . -type f -executable | /usr/lib/rpm/redhat/brp-mangle-shebangs I also updated the copyright notices as needed. 1. https://fedoraproject.org/wiki/Changes/Make_ambiguous_python_shebangs_error Fixes: 1ca0323e7c29 ("Require Python 3 and remove support for Python 2.")
