Well, Debian 10 (buster) was launched this year, and still comes with python2
(with is the default):

	$ ls -la /usr/bin/python
	lrwxrwxrwx 1 root root 7 Mar  4  2019 /usr/bin/python -> python2

I think Debian devs will keep it maintained for a while, as this is a LTS
distro.

Then we need to change the scripts, as they're currently pointing to
/usr/bin/python instead of /usr/bin/python3. At least on the distros I
use myself, this doesn't point to /etc/alternates. Instead, it is just
an alias to python2.

Thanks,
