Installation of FreeFem++ on Ubuntu virtual machine

Hello,
I am new to the forum. I am trying to install FreeFem on my ubuntu virtual machine by following the directions from the installation website Installation guide.
Everything looks fine until I proceed with : “make petsc-slepc”. At this point I receive the following message:

“Makefile:24: Makefile.inc: No such file or directory
make: *** No rule to make target ‘…/…/config.status’, needed by ‘Makefile.inc’. Stop.”

I would appreciate if anybody could help me with this, please.
Thank you for your time!
