```

For reference, Rocky installs Luminous (12.2.11-0) which works fine.

[Michal Nasiadka (mnasiadka)]

Situation in Kolla:
Ubuntu/Stein: Luminous
CentOS/Stein: Nautilus (Source RDO)

Ubuntu/Train: Nautilus
CentOS/Train: Nautilus

So - Bharat, if you use Ubuntu - it has a chance of working (or CentOS/Rocky)...
