I'm having issues with lab 3.3, following the guide the first issue i have is "openstack" is not installed:


ubuntu@devstack-cc:~$ cd ~/devstack/
ubuntu@devstack-cc:~/devstack$ source openrc admin
WARNING: setting legacy OS_TENANT_NAME to support cli tools.
ubuntu@devstack-cc:~/devstack$ openstack
The program 'openstack' can be found in the following packages:
 * python-openstackclient
 * python3-openstackclient
Try: sudo apt install <selected package>

 

After installing "python-openstackclient" I was able to start the openstack utility, but failed to create the project.


ubuntu@devstack-cc:~/devstack$ openstack
(openstack) project create CallCenter
Discovering versions from the identity service failed when creating the password plugin. Attempting to determine version from URL.
Could not determine a suitable URL for the plugin
(openstack)

 

I'm not sure how to proceed.

    Hello,

    Thank you for letting us know about this issue. It seems with Pip moved to version 10 it has caused some errors. Instead of a check script looking at the values the script was doing a string comparison, so version 10 was interperated as 1, which would be less than the minimum version 6. Its' a bug. The fix is to edit line 336 of /home/ubuntu/devstack/inc/python and change one word from strip to split: 

    which is to edit /home/   line 336 from:         

                         print(pip.__version__.strip('.')[0])")

    to

                          print(pip.__version__.split('.')[0])")

    Here is the bug:

    Here is the fix in detail:

    https://review.openstack.org/#/c/561411/3/inc/python

    This seems to be causing a secondary issue with the version of psutils, which is not installed via pip, but instead via a system utility. https://bugs.launchpad.net/devstack/+bug/1763966

    It would seem that as it was installed outside of OpenStack, the ./stack.sh script is unwilling to update the software. 

    The fix seems to be removing the apt package and installing the newer pip package. 

    sudo apt-get remove python-psutil

    sudo pip install psutil

    I did a ./unstack.sh, ./clean.sh. Then removed the apt package and installed the pip version of psutils. When those finished I ran the ./stack.sh script again and it seems to have worked.

    I have let the infrastrucure team know about the issue, i'm sure they will implement the fix soon. It may take a bit to test and roll out the fix. 

    Regards,
