Stack.sh falhou no Pike (DevStack)

Question

Stack.sh falhou com Pike

Estou tentando implantar o OpenStack em uma máquina virtual com Ubuntu versão 18.04.4 na versão mais recente do VirtualBox

A instalação do Stack.sh falha com esta mensagem

//git.openstack.org/openstack/keystone.git/opt/stack/keystone --branch stable / pike

conforme resolvo, falha na clonagem do Keystone

Qualquer ajuda seria apreciada
