This package contains a script with unversioned Python shebang.
The 2.x series of Python is due for deprecation and will not be maintained by upstream past 2020. As part of this, there is an on-going discussion in Python community to recommend soft-linking python to python3 on newer distributions.
If/when Debian starts following this recommendation, the specified script will be broken. However, please do not update this script for the time being.
