+Some scripts rely on /usr/bin/pyhton.
+
+python2 package provides /usr/bin/python as a link to /usr/bin/python2
+so there is no any issue here, but we do not want python2.
+
+python3 package do not provide /usr/bin/python, only /usr/bin/python3.
+
+To make things work we need to change shebang '#!/usr/bin/env python' to
+'#!/usr/bin/env python3'.
+
+This is a longstanding issue, one of the first traces to it could be seen
+here [1] and here [2].
