Re: The transition to add support for Python 3.6 is beginning

Hi Michael,
thanks for all the work on this.
I checked packages in your list that I often touch and found openvswitch:

It fails with:

Copying ovs.egg-info to /<<PKGBUILDDIR>>/debian/python3-openvswitch/usr/lib/python3/dist-packages/ovs-2.7.0.egg-info
Skipping SOURCES.txt  running install_scripts  /bin/sh: 2: cd: can't cd to python  debian/rules:84: recipe for target 'override_dh_install' failed  
That is [1] that I fixed in [2].
In general I wonder, other than your work of fixing these issues one-by-one, will you just re-upload new versions of the remaining failed packages iteratively every now and then to see things if like that resolved? Or do you need us other devs to notify you in any known case?

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.

Once the failures are accounted for, we can flip the switch to make python 3.6 the default in the archive.

Hi everyone,

The process of adding Python 3.6 as a supported version has begun.

The transition tracker is here:

and I'm currently working my way down the list.

I did a test rebuild of all/most dependent packages in a ppa:

And compiled some terse notes on the failures here:

And help resolving the failures would be appreciated (especially pandas!)
