Ubuntu: Ubuntu 14.04 Software Center Crash



Question:

I have had a problem with my ubuntu software-center for a while now. It refuses to start completely. So i have looked into all the web dungeons for answers with failed attempts in recovery. First I will start with the error i get when running software center on the command line. This is what i get:

2014-10-01 14:08:35,558 - softwarecenter.ui.gtk3.app - INFO - setting up proxy 'None'  2014-10-01 14:08:35,681 - softwarecenter.fixme - WARNING - logs to the root logger: '('/usr/lib/python2.7/dist-packages/dbus/proxies.py', 410, '_introspect_error_handler')'  2014-10-01 14:08:35,681 - dbus.proxies - ERROR - Introspect error on com.ubuntu.sso:/com/ubuntu/sso/credentials: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Process /usr/lib/ubuntu-sso-client/ubuntu-sso-login exited with status 1  Traceback (most recent call last):    File "/usr/bin/software-center", line 130, in <module>      app = SoftwareCenterAppGtk3(options, args)    File "/usr/share/software-center/softwarecenter/ui/gtk3/app.py", line 338, in __init__      self.icons)    File "/usr/share/software-center/softwarecenter/ui/gtk3/session/appmanager.py", line 66, in __init__      self.oauth_token = helper.find_oauth_token_sync()    File "/usr/share/software-center/softwarecenter/backend/ubuntusso.py", line 141, in find_oauth_token_sync      sso.find_credentials()    File "/usr/share/software-center/softwarecenter/backend/login_impl/login_sso.py", line 74, in find_credentials      self.proxy.find_credentials(self.appname, self._get_params())    File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 70, in __call__      return self._proxy_method(*args, **keywords)    File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 145, in __call__      **keywords)    File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 651, in call_blocking      message, timeout)  dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Process /usr/lib/ubuntu-sso-client/ubuntu-sso-login exited with status 1  

This is are the solutions that i have tried without success:

1st:

sudo apt-get purge software-center  sudo apt-get update  sudo apt-get dist-upgrade  sudo apt-get install software-center  sudo dpkg-reconfigure software-center --force  

2nd:

sudo apt-get install -f  

3rd

sudo pip install --upgrade oauthlib  

4th

gksudo software-center  

Will appreciate any help in getting this problem solved. All other solutions that come will try them and if they don't work will add them to the list here.

Some suggested solutions that i have tried and not worked:

1st

sudo chmod -R +rx /usr/local/lib/python2.7/dist-packages/   

2nd

sudo chown -R $USER:$USER /usr/local/lib/python2.7/dist-packages/  

3rd

sudo apt-get install --reinstall python-ubuntu-sso-client ubuntu-sso-client ubuntu-sso-client-qt  

After helpful insight, i have been directed to this link here that shows this being a bug and there is a bug report on it. So it seems we shall have to wait and see. If anyone has any hacks through this please post it here.

1st

Use an alternative package manager and synaptic package manager is recommended.

sudo apt-get install synaptic
