I noticed the same problem and removed python-wxgtk2.6 hoping it'd fix it, but then python cannot find any "wx" module at all!
Apparently it's a problem with the alternatives: python-wxgtk2.6 provides wx2.7.pth (where 2.7 stands for the _python_ version) and python-wxgtk2.8 provides wx.pth (no version here at all). So with python-wxgtk2.6 and python-wxgtk2.8 installed you get this: $ head /var/lib/dpkg/alternatives/wx* ==> /var/lib/dpkg/alternatives/wx2.7.pth <== auto /usr/lib/python2.7/dist-packages/wx.pth /usr/lib/wx/python/wx2.6.pth 26 ==> /var/lib/dpkg/alternatives/wx.pth <== auto /usr/lib/wx/python/wx.pth /usr/lib/wx/python/wx2.8.pth 28 ============================ /usr/lib/python2.7/dist-packages/ is actually the place where python look for the modules. So python-wxgtk2.8 gets kicked out by python- wxgtk2.6 . There is obviously something wrong, as the 2 packages should provide alternatives to the same thing. Maybe making python-wxgtk2.8 an alternative for wx2.7.pth (/usr/lib/python2.7/dist-packages/wx.pth) instead of wx.pth is the most compatible way? Note, as a workaround here is how I get python-wxgtk2.8 seen by python: sudo apt-get remove python-wxgtk2.6 sudo ln -s /usr/lib/wx/python/wx.pth /usr/lib/python2.7/dist-packages/wx.pth -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/948944 Title: after upgrade from oneiric python applications may use the wrong version of wxpython and fail as a result To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/wxwidgets2.8/+bug/948944/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
