An update to this. I notice that it crashes when trying to spawn /usr/lib/ubuntu-sso-client/ubuntu-sso-login
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Process /usr/lib/ubuntu- sso-client/ubuntu-sso-login exited with status 1 so I tried running this on its own and got Traceback (most recent call last): File "/usr/lib/ubuntu-sso-client/ubuntu-sso-login", line 67, in <module> from ubuntu_sso.main import main File "/usr/lib/python2.7/dist-packages/ubuntu-sso-client/ubuntu_sso/main/__init__.py", line 39, in <module> from twisted.internet import defer File "/usr/lib/python2.7/dist-packages/twisted/__init__.py", line 53, in <module> _checkRequirements() File "/usr/lib/python2.7/dist-packages/twisted/__init__.py", line 37, in _checkRequirements raise ImportError(required + ": no module named zope.interface.") ImportError: Twisted requires zope.interface 3.6.0 or later: no module named zope.interface. I then tried to install zope.interface using synaptic but it was already installed. Some searching had me thinking it should be installed in /usr/share/pyshared/zope/interface/ but this directory does not exist on my system even though there was a link to it in (sorry forgot where, I deleted it). So seems to me the issue is with trying to get /usr/lib/ubuntu-sso- client/ubuntu-sso-login working -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1298793 Title: Software Center won't launch 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1298793/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
