I was able to install a compute node on one ubuntu 14.04 desktop a few days age, but failed to install one on the other ubuntu 14.04 desktop now. I used the devstack juno, and the same localrc which succesfully did before (only changed IP address). Both desktops are ubuntu 14.04 linux physical machines. I got the failure errors in log below:

          devstack$ sg libvirtd '/usr/local ^M/bin/nova-compute --config-file /etc/nova/nova.conf' & echo $! >/opt/stack /statu ^Ms/stack/n-cpu.pid; fg || echo "n-cpu failed to start" | tee "/opt/stack/status/s ^Mtack/n-cpu.failure"^M

Here is some of installed packages as well as the versions: python-cinderclient==1.1.1 python-debian===0.1.21-nmu2ubuntu2 python-editor==0.4 python-glanceclient==0.14.3 python-keystoneclient==1.1.1 python-mimeparse==0.1.4 python-neutronclient==2.3.12 python-novaclient==2.31.0 python-openid==2.2.5 python-openstackclient==1.0.1 six==1.9.0 stevedore==1.3.0

Could anyone help me to fix the issue? Thank you!

"'Module_six_moves_urllib_parse' object has no attribute 'SplitResult'"

Looks like a version mismatch, perhaps temporary. Clean up and try running stack.sh again.

I found python lib installed on two locations: /usr/lib/python2.7 and /usr/local/lib/python2.7. The version of six on /usr/local/lib/python2.7 is 1.9.0. I overwrote the six package on /usr/lib/python2.7 with the version 1.9.0. It fixed the issue.
