See attachment for console output of problem.

I am not sure if this is update-manager or aport problem.
Due to that bug no cleanup was performed; my /etc/apt/sources.list still has the
11.10 (oneiric) packages listed.

Thanks for your report.

I'm unable to reproduce it locally. Could you please attach an archive of the directory /var/log/dist-upgrade to this report.
That might be the same error seen with the auto upgrade tests http://people.canonical.com/~mvo/automatic-upgrade-testing/current/

Thanks in advance.

Is it a btrfs install of Natty ?

No it was just a try to get 11.10 to be alpha tester there...

And btrfs was not installed and is not installed now.

In the attachment there is the zipped /var/log/dist-upgrades/*

[Jean-Baptiste Lallement (jibel)]

Thanks for the logs.

Michael, I can't reproduce, could you have a look at it ?

[LIU Aifu (laf163-gmail)]

I have the same problem.

[Tristan Hill (stan)]

Maybe this has been spotted, but it looks like

        if not apt_btrfs.snapshots_supported:
            logging.debug("btrfs snapshots not supported")
            return

should be

        if not apt_btrfs.snapshots_supported():
            logging.debug("btrfs snapshots not supported")
            return

i.e. missing ()

[Dimitri John Ledkov (ex-credativ) (dle-credativ)]

Same here. And I agree with Tristan. Can't test it easily though, cause the file is redownloaded each time...

ps. see ya in the office tristan ;-)

[Jean-Baptiste Lallement (jibel)]

Fixed in:

update-manager (1:0.151.7) oneiric; urgency=low

  * fix apt-btfs-snapshot releated crash
