keystone-manage db_sync command failed

[Swami Reddy]

When I ran stack.sh from the latest devstack, the below error shown:

Looks like this is similar to https://bugs.launchpad.net/nova/+bug/1083054

I was only able to reproduce this by installing six v1.6.1 which is explicitly unsupported by keystone (which requires >= v1.7.0 in requirements.txt). The latest version of six is v1.8.0:

  https://pypi.python.org/pypi/six

Can you confirm the version of six that you're running?

  $ python -c "import six; print(six.__version__)"

[Swami Reddy (swamireddy)]

Iam using the latest six ie six-1.8.0 and still this problem seen

[Vincent Hou (houshengbo)]

It happens on my machine as well.

[Swami Reddy (swamireddy)]

Vincent Hou - As per the Dolph Mathews comment - check the version of six pkg. If you use the six version >= 1.7.0, it works.

[Dolph Mathews (dolph)]

Swami: thanks for the follow up! This one was a little befuddling :)

[Swami Reddy (swamireddy)]

Mathew: That's correct - Its confusing issue. Even though latest version of six installed using the easy_install, still this issue won't be fixed. This should be fixed using the Ubuntu package update manually.

[Brianna Poulos (brianna-poulos)]

I was having the same issue on Ubuntu 14.04 with the latest updates. I had version 1.5.2 installed, but using pip to try to upgrade it didn't work.

$ python -c "import six; print(six.__version__)"
1.5.2

I figured out exactly where it was being pulled from and deleted it.

$ python -v -c "import six; print(six.__version__)"
...
import six # from /usr/lib/python2.7/dist-packages/six.py
...
$ sudo rm -f /usr/lib/python2.7/dist-packages/six.py /usr/lib/python2.7/dist-packages/six.pyc

Python then used 1.8.0 from a different location (from /usr/local/lib instead of /usr/lib):

$ python -c "import six; print(six.__version__)"
1.8.0
$ python -v -c "import six; print(six.__version__)"
...
import six # precompiled from /usr/local/lib/python2.7/dist-packages/six.pyc
...

[Swami Reddy (swamireddy)]

As remember the stack.sh install the old version of six only. You can
update the apt repo with latest six version to work

[Gil Vernik (gilv)]

I have exactly the same problem.

[Swami Reddy (swamireddy)]

What version of six are you using?
==
$ python -c "import six; print(six.__version__)"
==

NOTE: pip install six latest version won't work. You just install the Ubuntu package of six should be updated to the latest version.
