Comment out the following lines.  

local.conf

[[local|localrc]]

#FIXED_RANGE=10.10.128.0/20 #Range for private IPs

#FLOATING_RANGE=192.168.100.128/25 #Range for public IPs

    Thank you for posting a fix.

    If you use DevStack with Neutron networking you no longer need to pass parameters for fixed and floating IP addresses. These values are still necessary if you use Nova networking as would be found in the Liberty release.

    Did an unstack.sh and clean.sh. Commented out the local.conf as specified. Still getting keystone errors and the UI is just the generic Ubuntu/Apache banner.

    Please post other errors or warnings from the stack.sh.log file. I see the portion where keystone is failing, but the networking issue that probably led to the issue is not shown.   When the network is configured with the stack.sh script there are a few changes made. The clean.sh and unstack.sh scripts do not undo those changes.   

    Please select the "Start over" button in the upper right of the window. After running the lab again, should you get an error, please look farther up the log to find other errors that would prevent Keystone from starting properly.

    For some reason the barbican release, even the older liberty version, ties to use  API v3 commands. It shouldn't, but still does. As a result, please omit or comment out that line from the local.conf file. 

    If barbican were to work properly we could call the older version via the local.conf file with an entry like this:


    enable_plugin barbican https://github.com/openstack/barbican stable/liberty

    Thank you as usual Serewicz, that did the trick, how do you figure these things out? when I face a problem like this, there is no way I can relate barbican to the issue on the Horizon webpage, I would appreciate it if you share some of your tricks with us :-)

    I'm also having issues with Lab 2.1, as suggested in other posts here, I tried to install devstack, using below git clone command :

    git clone https://git.openstack.org/openstack-dev/devstack -b stable/liberty

    I got whole bunch of errors at the end but much to my suprise, I could actually access the Horizon page and login to it but now the new problem is that it is not able to detect anything , when I click on any button , it says "Unable to retrieve instanses"

    I tried to Start Over the lab once and still observing the same issue here. at least this error can be reproduced , i'm glad there is some consistency :-)

    Any help would be very much appreciated

    Here is the local.conf file :

    Log files and lots and lots of time working with the product. OpenStack changes so fast documentation cannot keep up. Review output and log files, look for errors that happen before the obvious error to determine what kind of thing was happening and some guessing. I wish I could pass along a secret sauce recipie, but its mostly days and days of working with it until the stuff makes sense.

    Glad it worked! Thanks!
