Devstack installation fails : stack.sh failed Error on exit

Question

I'm currently facing a problem while installing Devstack (for an assignement) During the installation, when running the /stack.sh command on terminal, the following error appears:

stack.sh failed Error on exit World dumping... see /opt/stack/logs/worlddump-2022-01-08-133559.txt for details

when opening the .txt file : '''

I've tried solutions found on stackoverflow but this error perssists. Please note I'm an absolute newbie when it comes to Ubuntu and devstack ..all I want for now is to access the Dashboard and I'd be pretty happy if I could do at least that.

Thank you for your time.

PS: I have followed all the steps mentionned here : https://computingforgeeks.com/openstack-deployment-on-ubuntu-with-devstack/

Answer 1

post your devstack/local.conf Are you installing in a VM (ubuntu (which one)?) (you probably should as devstack makes a lot of changes)

you can undo changes with unstack.sh , then optionally clean.sh , and if really cleaning up: rm -rf /opt/stack (not normally necessary).

Also recheck networking before rerunning stack.sh (ip link; ip a, ip route)
