SC silently fails to start: softwarecenter.backend - ERROR - aptdaemon import failed

[Paul Sladen]

Binary package hint: software-center

Freshly reinstalled natty, attempting to run Software Centre gives no result. Trying again from the command-line produces:

  $ software-center
  2010-12-14 03:01:01,958 - softwarecenter.backend - ERROR - aptdaemon import failed
  Traceback (most recent call last):
    File "/usr/share/software-center/softwarecenter/backend/aptd.py", line 39, in <module>
      from aptdaemon.defer import inline_callbacks, return_value
  ImportError: No module named defer
  Need the latest aptdaemon, try "sudo apt-add-repository ppa:software-store-developers/ppa" to get the PPA

seems likely that something is missing a hard or versioned dependency.

  aptdaemon = 0.40+bzr529-0ubuntu1
  software-center = 3.1.3

Hit this again, it could be the Python 2.7 turmoil.

I was unable to recreate this bug report with software-center version 3.1.6. Could you please test this again with that version?

Thanks for your bugreport.

Is this still a problem? This sounds like this was churn during the development.
