This package contains a script with unversioned Python shebang and thus defaults to using Python 2. The 2.x series of Python is deprecated and apart from rare cases, will not be supported in Debian Bullseye. . If the script in question is compatible with Python 3, please modify it to use /usr/bin/python3 instead. If it only is Python 2 compatible, please modify it to use /usr/bin/python2.
