python-nova is missing gettextutils.py breaking nova-compute-flex

[Lee Revell]

When nova-compute-flex is installed nova-compute cannot start. The error logged is:

This appears to be due to /usr/lib/python2.7/dist-packages/nova/openstack/common/gettextutils.py not existing. With openstack juno from the ubuntu cloud repo, python-nova provided this file.

Also missing are:

/usr/lib/python2.7/dist-packages/nova/openstack/common/{log.py,importutils.py,jsonutils.py,strutils.py,timeutils.py}

Was there some major code refactoring that the the python-nova package didn't pick up on?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[gustavo panizzo (gfa)]

works on juno, does not work on kilo

[Mark Vanderwiel (vanderwl)]

What release is this? juno, kilo, liberty? I ran a couple of tests with Kilo and the ubuntu cloud archive and don't seem to hit this issue.

[Lee Revell (rlrevell-k)]

Kilo on Ubuntu 14.04.2 from this repo:

# cat /etc/apt/sources.list.d/cloudarchive-kilo.list
deb http://ubuntu-cloud.archive.canonical.com/ubuntu trusty-updates/kilo main

Confirmed still broken.

Does the file /usr/lib/python2.7/dist-packages/nova/openstack/common/gettextutils.py exist on your system? Can you pastebin nova-compute.log of the nova-compute-flex driver startup?

Anyone found a work around for this bug on 14.04.2 LTS using repo "deb http://ubuntu-cloud.archive.canonical.com/ubuntu trusty-updates/kilo main". I just upgraded from juno to kilo and this bug is still an issue.
