binary packages. Ubuntu packages come from Debian unchanged, so your<br>
question can be reduced to Debian packaging.<br>
<br>
We're the wrong people to ask. It's not a skill any of us at Sugar<br>
Labs have, otherwise we would have done it by now.<br>
<br>
The people who know how to do this are Debian and Ubuntu package<br>
developers.<br>
<br>
I've tried asking one of the Debian developers but they were too busy<br>
to give private assistance. Private assistance does not scale, so the<br>
return on investment is meagre.<br>
<br>
I suggest you try these things;<br>
<br>
1. write a throw-away script to download all Debian packages that<br>
depend on Python 2 or Python 3, intersect a union of source packages<br>
that support both versions, and then list those packages that contain<br>
<a href="http://configure.ac" rel="noreferrer" target="_blank">configure.ac</a> in the source package,<br>
<br>
2. review those Debian and Ubuntu source packages that are used to<br>
generate binary packages for both Python 2 and Python 3, and list the<br>
package design patterns that you observe,<br>
<br>
3. contact the Debian developers using their mailing lists, or other<br>
methods,<br>
<br>
4. engage in the Debian project by reporting a bug that asks for<br>
packaging of a new version of the toolkit; currently 0.112 is<br>
packaged.<br>
