Install salome in Ubuntu 20.04 (in vbox)

Dear experts,

I tried to install salome in my ubuntu 20.04 system. But when I used ./salome command, I got a message saying:

Warning, no type found for resource "localhost", using default value "single_machine"
double free or corruption (out)

And for that although the salome page is opening, but it is not getting installed in my machine.

Can you please guide me ?
