Seems that apport take care only of the beginning of the error message :

it identify:
- aptdaemon crashed with AttributeError in _inline_callbacks()
- but ignore the end of the error : 'NoneType' object has no attribute 'send'

and does not care about "fix released" field (at least for this package)

Definitely occurring on 12.04 beta (Precise - aptdaemon 0.43+bzr805-0ubuntu1) with slightly different line numbers:

Traceback:
 Traceback (most recent call last):
   File "/usr/lib/python2.7/dist-packages/defer/__init__.py", line 475, in _inline_callbacks
     result = gen.send(result)
 AttributeError: 'NoneType' object has no attribute 'send'

[simon (mrmoor4)]

this bug occours in ubuntu 12.04 Beta 2.
It happens by opening the software center.

[Raimund Sacherer (hatrix)]

Hello, this happens in 12.04 Release to!

[marco python (marco-python-x)]

Error message occurs on fresh installed 12.04-release without any user actions (just after boot).

[marco python (marco-python-x)]

Also occurs on software center start.

[Nick (nick222-yandex)]

Also on update-manager start.

[Fabien Tassin (fta)]

looks similar to bug 971748, for which i provided more information.
Please dupe one if needed.

[John Coulthard (retired)]

This occurs at startup for my 12.04 system. Part of the reporting procedure has a checkbox for "ignore future problems of this type". Do the maintainers prefer I continue to report it for as long as it keeps happening?

[Ted Bodfish (tedbs)]

12.04 Desktop - no problems - installed latest updates - reboot required. After reboot, ubuntu waits (twice) for networking, then starts without NetworkManager and this problem occurs. Rebooted again, same wait for networking and this problem still occurs.

[joherrer (joherrer)]

I've been having same syntomps as Ted Bodfish, since installing updates last week (I'm not sure if May 31st or June 1st).
My Precise is installed on a desktop, with a Nvidia GEForce 3700 video card, AMD processor.

[Manjul Apratim (manzdagratiano)]

Fresh install of Precise amd64 here with the same issue... I have not looked at the code for aptd or anything, but IMHO, it smells of a Python2 -> Python3 transition issue?

Dearest Canonical,

First and foremost - this is my first time to report anything with Ubuntu, and I only do it because the system asked me to comment. I am a developer of software for 31 years, and have worked under Linux, Java, MySQL, since 1999. I run a college (owner) in Kenya, called Digital Age Institute, the top most college in Software Development in Africa, in which capacity I was requested to comment on this bug :-).

Thanks guys, for Ubuntu. It is a gift to the world. No jokes. It is a gift. Secondly - in professional regards to this particular error, I did not know that it happened. I would guess that it is related to the only activity I did last week - namely installing an Adobe plug in.

Have a wonderful day, dear developers of Ubuntu. Great job. If we can contribute to the development, I would appreciate if you can give us guide lines - we have more than 700 students who have graduated yet - all of them in Ubuntu, Java, MySql - and professional software development disciplines.

Warmly
