Bug Description

Binary package hint: software-center

Hi,

I was cleaning up and striping down my ubuntu installation and i've found a dependency missing for software center python-launchpadlib.

When apport isn't installed (since it's only recommand from ubuntu-desktop package) you can remove python-launchpadli without dependency problem :

gfarmerfr@GNU-BoX:~$ sudo deborphan -a | grep launchpadlib
main/python python-launchpadlib

gfarmerfr@GNU-BoX:~/Téléchargements$ dpkg -I software-center_2.1.17_all.deb

 Description: Utility for browsing, installing, and removing applications
  The Ubuntu Software Center lets you browse and install thousands of
  free applications available for Ubuntu. You can view available
  applications by category, or search quickly by name or description.
  You can also examine the applications already installed, and remove
  those you no longer need.
  .
  To install or remove software using the Center, you need administrator
  access on the computer.
 Python-Version: current

so i've removed it

but then software-center won't start :

gfarmerfr@GNU-BoX:~$ software-center
Traceback (most recent call last):
  File "/usr/bin/software-center", line 84, in <module>
    from softwarecenter.app import SoftwareCenterApp
  File "/usr/share/software-center/softwarecenter/app.py", line 62, in <module>

  File "/usr/share/software-center/softwarecenter/backend/launchpad.py", line 32, in <module>
    from launchpadlib.launchpad import Launchpad
ImportError: No module named launchpadlib.launchpad

and when i've installed apport to report this bug apport triggered the install of python-launchpadlib :

gfarmerfr@GNU-BoX:~$ sudo aptitude install apport
Les NOUVEAUX paquets suivants vont être installés :
  apport python-apport{a} python-launchpadlib{a} python-problem-report{a}

Prendre :4 http://archive.ubuntu.com/ubuntu/ maverick/main apport all 1.14.1-0ubuntu6 [56,1kB]

....

So i think python-launchpadlib should be a direct dependency from software-center ?

Either i'm wrong or you miss the "lib" from python-launchpadlib in the debian control file at rev1114 ?

Sorry to say but this bug is not fixed since I can still suppress python-launchpadlib with software-center 2.1.22
without a warning of aptitude/synaptic/whatever wanting to suppress software-cebter to resolve the conflict.
Btw software-center still crash with exact same error without python-launchpadlib.

gfarmerfr@GNU-BoX:~$ software-center

I think that when the lp branch of Mohamed (that would fix the dependency bug) was merge the meaning of this bug was misunderstood and python-launchpadlib was demoted to only a "suggest" package instead of a "depend" one.
Mohamed do you agree on this ?

I had the same error with a freshly installed 10.10 today, and eventually I have made it work somehow.

Starting software-center (3.0.7) from terminal gave:

pbekesi@csacsi-desktop:~$ software-center
Traceback (most recent call last):
  File "/usr/bin/software-center", line 88, in <module>

    from launchpadlib.launchpad import Launchpad
ImportError: No module named launchpadlib.launchpad

I reinstalled python-launchpadlib (1.6.1-1) to see if it fixes, but after I did this, starting software-center resulted in:

pbekesi@csacsi-desktop:~$ software-center

    class DatetimeJSONEncoder(simplejson.JSONEncoder):
AttributeError: 'module' object has no attribute 'JSONEncoder'

I tried reinstalling software-center, but the result was the same. After some googling, I also reinstalled the package python-simplejson (2.1.1-1)

Now it if starting up fine except for maybe the below output, but besides that it's ok.

pbekesi@csacsi-desktop:~$ software-center
