Public bug reported: Just a few days ago I did a fresh install of Ubuntu 12.04. At first it worked, but now I can't install or remove any program through Ubuntu Software Center. I just click "install" or "remove" button , or even "use this source", and nothing happens.
I will try to describe some symptoms so you can help me. 1) Everytime I click "install" or "remove" in USC, I get this messages in syslog: May 21 11:54:54 ******* dbus[848]: [system] Activating service name='org.debian.apt' (using servicehelper) May 21 11:54:54 ******* dbus[848]: [system] Activated service 'org.debian.apt' failed: Launch helper exited with unknown return code 1 2) Apt-get works flawlessly, except that now it started to throw me that message everytime after I install something: Error: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1 It just throws it, but the installation happens. 3) Running gksudo software-center and trying to install something gives me this in terminal: 2012-05-21 11:58:09,577 -

WARNING - download failed: '<class 'gi._glib.GError'>', 'Operation not supported' 4) I believe it is something Python related, since I am also experiencing some weird issues using python-pip package. Actually, entering "ubuntu-bug software-center" gives me: ERROR: Could not import module, is a package upgrade in progress? Error: No module named pkg_resources -- Which is very similar to "pip" (from python-pip package) output: Traceback (most recent call last): File "/usr/bin/pip", line 5, in <module> from pkg_resources import load_entry_point ImportError: No module named pkg_resources -------------------------------------------------------------------------------------- So, what I've tried to solve it? Until now, I've tried this commands: sudo apt-get update sudo apt-get upgrade sudo apt-get install --reinstall software-center sudo apt-get purge software-center; sudo apt-get install software-center sudo apt-get install --reinstall apt rm -r ~/.cache/software-center sudo apt-get install ubuntu-desktop gksudo software-center sudo apt-get purge python-pip; sudo apt-get install python-pip sudo apt-get purge python-setuptools; sudo apt-get install python-setuptools I also did an apt-get install --reinstall for all dependencies of software-center. But the problem goes on. =/ At last, I send you the output for the commands on https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure below.
