When I ran the installation script, candi.sh, I got the error message below. However, I managed to successfully install a newer version of petsc externally.

Now the issue is: I would like to the script to avoid downloading and trying to install the default version petsc and instead indicate the path where I installed so it can add it as a component.

Can this be done?

Yes, deal.II is happy to use an externally installed version of PETSc. In fact, the easiest way to install deal.II with PETSc is to just use
  apt install petsc-dev
or the equivalent on whatever system you are using. If installed this way, deal.II's cmake script will find it and use it.

Best
