[Openstack] Fatal error during container create (ansible-openstack on bionic)

Hi Mohammed,

Xenial doesn't fit my needs in other ways, so reverting to it isn't an 
option, and I also want to use bionic's spin of openstack rather than 
run with packages from another repo, nor wait for an unspecified period 
for Rocky's appearance. I am prepared to invest some time in debugging 
this build, but I was hoping for some assistance here out of courtesy.

The only reason I looked at os-a was that configuring openstack on its 
own was unfathomably complex. Even with ansible it is still very complex 
for what I feel should be a simple task. I don't really understand why 
there isn't a default usable (i.e. one-box cloud) configuration in the 
.rpm/.deb packages which users can then extend and adapt, as with other 
similar tools.

Where would I look for the current work on the os-a rocky update? 
perhaps I can derive something useful from that.

Regards,
Ruth
