  • If ./rejoin-stack.sh is not working, Just navigate to /opt/stack/keystone/bin & execute keystone-all .

  • Thank you, thank you for sharing this. You saved me from reinstalling Ubuntu/Icehouse numerous times!!!!!!!!!!!!

  • i have tryed as you suggested on 12.10, now i can ./rejoin-stack.sh, but if i try to access to horizon, the login fails and ubuntu says kayston-all is closed unexpectedly

  • It seems solved by using ubuntu 12.0.4. I'll try your solution to with 12.10

  • Are you running as root?
    Copy stack-screenrc from /opt/stack/devstack/stack-screenrc in to devstack and run re-join.
    # cp /opt/stack/devstack/stack-screenrc devstack/
    #cd devstack
    # ./rejoin-stack.sh

  • Hi. I got this error "Login Error An error occurred authenticating Please try again later" once i restart ubuntu after openstack installation using devstack. If i try to run "rejoin", i got a massage says about "have you run stack.sh yet?", and so i can't run "rejoin".
    How can i fix? Tnx a lot, and sorry if i'm not clear, i'm not english
