I had the same problem. The crux was that there was obviously and old version of virtinst still half-installed after the upgrade from hardy. The file /usr/lib/python2.6/dist-packages/virtinst-0.300.2.egg-info for example was present on my system. I solved the problem as follows:
# Will remove ubuntu-virt-mgmt and virt-manager as well sudo aptitude purge virtinst sudo rm /usr/lib/python2.6/dist-packages/virtinst-0.300.2.egg-info sudo rm -Rf /usr/lib/python2.4/dist-packages/virtinst* sudo rm -Rf /usr/lib/python2.5/dist-packages/virtinst* sudo rm -Rf /usr/lib/python2.6/dist-packages/virtinst* # Will re-install virt-manager as well sudo aptitude install ubuntu-virt-mgmt Seems to be a bug in python-support. -- virt-manager won't run because of wrong version of python-virtinst https://bugs.launchpad.net/bugs/576394 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
