Hi,

I'm wondering, why the python packages for version 2 and 3 don't use the update-alternatives script.

Any reason for this?

I haven't found anything in the package itself nor on mailing lists. Probably I've missed some. You just looked at the wrong lists then - the discussion was heated :)

Maybe this was on purpose as Python2 isn't a complete replacement for Python3 (and vice versa). On the other side, I assume, not all Java runtime environments are always compatible. However, still, you can use this:

The java runtimes are supposed to be compatible. They might error out if the target version of the jar is unsupported, but the (discussed) problem with python 2 and 3 is that they might interpret the same syntax differently - and not error out, but create hidden bugs.

Bug? Feature? Design decision? Hope someone can enlighten me. :))

Thanks Stephan and Karl for the pointers!

Indeed, I looked at the wrong list. :))

There is also an upstream discussion around this which might be interesting: https://www.python.org/dev/peps/pep-0394/ Cheers, Kristoffer
