How do I find my PGI version? for Gaussian 16

[mahesh]

Hi,

I stopped using linux (and most of the PC) for a while because I was too busy.
Gaussian 16 needs PGI version 17.7 and on Ubuntu g16 is not supported.

I did not find PGI in the software list. I think it is inside some other package (gcc8-fortran or something).
How do I know I can use gaussian or not?

Thanks.
