Hi Everyone,  

I am currently trying to setup in all-in-one development environment for OpenStack on a Debian VM.  The VM has 16 GB RAM and 4 CPUs. However, I face an error while trying to run FORCE=yes ./stack.sh. 
I get an error that keystone does not start. This causes the entire process to fail. Requesting assistance in solving this issue. 

I am following the this guide: https://docs.openstack.org/devstack/latest/guides/single-machine.html

PFA the error log and error message on the terminal. 



Thanks in advance,
Ishan
