Open Stack

Hi Alex,
we are trying on centos 7/8, and similar commands for centos 7/8 is not
working. Can you please suggest related commands for the same?
we have tried with yum/dnf in centos 7/8.

Just to confirm again we are using the stein release on centos 7 where we
want to use ipv6 or dual-stack if possible.
Thanks once again for your help.
