supertuxkart-data.noarch: W: non-executable-script /usr/share/supertuxkart/data/po/update_desktop_file_appdata.py 644 /usr/bin/env python3
This text file contains a shebang or is located in a path dedicated for
executables, but lacks the executable bits and cannot thus be executed.  If
the file is meant to be an executable script, add the executable bits,
otherwise remove the shebang or move the file elsewhere.

supertuxkart-data.noarch: W: pem-certificate /usr/share/supertuxkart/data/cacert.pem
Shipping a PEM certificate is likely wrong. If used for the default
configuration, this is insecure ( since the certificate is public ). If this
is used for validation, ie a CA certificate store, then this must be kept up
to date due to CA compromise. The only valid reason is for testing purpose, so
ignore this warning if this is the case.
