Thanks for taking the time to report this bug in Ubuntu. It looks like a local install of keystone in /usr/local/bin is interfering with the upgrade process:
File "/usr/local/bin/keystone-manage", line 4, in <module> import pkg_resources Please remove/resolve this issue and then run: sudo apt-get -f install I'm marking this bug as 'Invalid' as this is a local environment issue.
