Re: Python 3 only for 16.04

Hi Andres

Yes, Scott's been working to purge python 2 from the server images during the last cycle even.   IIRC, we had a new dependency sneak in late 15.10 via LXD dependencies (cloud-init-tools) that he needs to fix yet.  

If you look at the blueprint & session notes you'll find server items (mostly tagged 'smoser'). 

Note: python 2.7 will still be available in the archive via apt-get for applications that still need it, this is just about defaults.

Hi Barry,

I was wondering how much of this is actually affecting server? Looking at the wiki/spreadsheet, all of the packages are Desktop related, where are there's no specifics for server. That being said, MAAS, for example, has dependencies that don't even support python3 upstream, as well as other dependencies that will require attention from the packaging perspective.

The MAAS team has already started doing some works towards being fully python3 compatible, although, however, it might be the case that we won't make it for xenial.

Also, CC'ing Jon Grimm to maybe help shed some light form the server perspective.

In today's UOS session on dropping Python 2 from the default
installs/seeds/images, we captured a bunch of work items.  For those of you on
the session, please look at both the wiki and blueprint linked below, and make
any additions or corrections you might find to my note taking.

You might also want to subscribe to the wiki page.  Of course, we welcome any
