nova-docker issue. Import error: no module named i18n
Hello,
I'm trying to install nova-docker driver, following the README file at https://github.com/stackforge/nova-docker (https://github.com/stackforge/nova-do...) . I followed all the steps, but when I restart nova-compute, the service doesn't start and I get the following error in the log file:

Does anybody know why this happen and what I can do to solve this problem?
Thank you.
UPDATE
As larsks said, I have changed the code in my nova-docker to previous the commit 9ce916c4 and the error now changed to this:

Does
novadocker/virt/docker/client.pyexist?Yes, but this was just a temporary error. I don't know how it happened and when I tried to restart nova-compute this error disappeared, even doing nothing. It was just very strange!
If I can exploit your helpfulness, I have another issue. It says: Docker daemon is not running or is not reachable (check the rights on /var/run/docker.sock). But nova user is in the docker group and I did chmod 666 to the sock file. And docker service is running. Do you know why this happen? Thanks
You should post that as a seperate questions so we don't clutter of this one with unrelated comments.
