Shipping Python 3 on the 12.04 LTS CD
Python plans for 12.04 LTS: Python 3.2 and 2.7 only. We dropped 3.1 in Oneiric and 2.6 in Precise. For 12.04 the goal is at least one desktop application destined for the default installation (i.e. CD images) to be ported to Python 3. Long term (14.04 LTS), we want Python 3.2 only on the CD, with 2.7 still available in main.

Precise notes: postponing all remaining work due to impending feature freeze and barry shifting gears to stable+1 maintenance. As time allows, I'll remark specific items as INPROGRESS and continue working on landing those changes upstream and in Debian. Porting u-m will continue in earnest for the Q-cycle.
update-manager is the selected application. Here is its (Python) dependency stack, with Python 3 status and some additional notes after chatting w/mvo.
- python-boto (maybe just for ec2 testing?)
status: port needed
mvo: can kill it off
- PyQt4
status: python3-pyqt4
- gconf
status: unknown
mvo: kill it off
- python-
status: port needed
mvo: or just call subprocess directly
mitya57: there's a more active project, and it supports python3: http://
- PyKDE4
status: Python3 port exists upstream - needs packaging, not sure why port to Qt?
mvo: port to qt
- aptdaemon
status: unknown
mvo: waiting for dbus, upstream wants to port it
* a really good start
- python-apport
status: pitti says problem_report.py needs bytes/str fixes
- python-debian
status: pending upstream review; http://
- python-mock
status: done by upstream/Debian in 0.7.2-1
- ??? check_new_
tests/
mvo: probably already dead
- mvo: maybe get rid of lsb-release in favor of `import platform`
- mvo: update-manager-text should die
