Bug#910940: sagemath-common: fails to start with error /usr/bin/env: ‘sage-python23’: No such file or directory

[Amaury Pouly]

Package: sagemath-common
Version: 8.3-3
Severity: important
Tags: upstream

Dear Maintainer,
the sage notebook fails to start because there is no sage-python23 installed
on my system. Can be reproduced by running
  sage --notebook
A similar issue was raised for other binaries (bug #902545) but for some reason
the notebook was not patched, maybe it was forgotten or it requires a special
treatement. The upstream version of this file also uses sage-python23
