Existence of "python2" is blindly assumed

[Malachi]

On Debian Sid 64 bit, the most recent development versions (about the last week or so, up to 3763) have been looking for python in a python2 folder (I assume to differentiate from python 3), so that when I start exaile, it immediately crashes.

Thanks for the good work!

This is the terminal output:
exec: 13: python2: not found

In fact, python2 is the name of the binary which was recently changed to accomodate the move to Python3 as default version.
However, Debian does not yet provide the python2 binary/symlink.

We should not blindly assume the existence of this one though and will think about a fix. At the same time you could file a report against Debian and request to add this symlink.

Just to clarify: various distributions have started to move to Python3, not Exaile.

I will. Thanks for the answer.

Confirmed in Ubuntu 10.10 as well.

The easiest thing might be to check if "python2" exists (in the launcher shell script, for example by calling "which python2" and seeing if the returned string has zero length), otherwise use just plain "python". This should always result in python 2.x.
