Hi all,

An update on the transition to Python 3.6: Python 3.6 is now a supported version in artful release, and almost all packages that build C extensions have been rebuilt (pandas is still a problem).

We have created a PPA where python3.6 is the default and rebuilt all python packages: https://launchpad.net/~canonical-foundations/+archive/ubuntu/python3.6-as-default/+packages and the next step is to fix all the failures this reveals.  The initial failing source packages are listed in http://paste.ubuntu.com/24903638/ although some of those have been fixed now.
 
The 100 or so failures are now summarised in https://docs.google.com/spreadsheets/d/1Y8dy5cyu8DrmTvT4CNSaVSP2ZZT79sYhT_rAQ19bFUQ/edit?usp=sharing, please do check if any packages you care about are on the list and fix any that you can see how to. Uploading fixes direct to the archive is preferred, but if you lack the rights to do that, attaching a bug to a debdiff and subscribe me (mwhudson on lp) and I'll sponsor it v. quickly!

We've fixed many of these now, and I've uploaded the change to make python 3.6 the default version in artful. Next step is getting this to migrate, see http://people.canonical.com/~ubuntu-archive/proposed-migration/artful/update_excuses.html#python3-defaults for that and please help fix anything that is preventing the migration (like whatever it is that breaks botch with python 3.6 as default...)

Cheers,
mwh
