Just wanted to add my input. I just recently noticed the same thing. Luckily i was just testing Zentyal, but when I installed python-apt after reading the error message, apt seemed to completely break. I would be curious on a workaround/fix for this as well.

Better workaround is to download newer python-apt from here [1] and install it manually with dpkg. The guest agent seems to work OK with it. There's much less chance of breaking something else, also newer python-apt will be picked-up automatically on upgrades. Tomas [1] https://packages.ubuntu.com/yakkety/python-apt
