Vsphere VCENTER Server virtual appliance installation Stuck at 80% (and/or RPM installation failed)

I tried to install an old ISO image of the Vcenter virtual appliance from the 2017 and I discovered it was not installable anymore.

The installation progress stuck at 80% and in the end it failed with RPM installation failed.

Reading around it seems a bug in the image itself, the setup process cannot change the root password and so cannot continue and it fails.

Solution (in my case) :

Simply download the latest VCSA .ISO from VmWare site
(I just installed this succesfully: VMware-VCSA-all-6.5.0-7119157.iso )

NOTE: also this version seems to stuck at 80%, it will take a long time to move from 80% but in the end it will be able to pass it and finish the installation
