Failed concretization of Spack environment

[atteggiani]

Description

While testing the future documentation for how to build a package with spack develop, I got into the following error when trying to concretize the ACCESS-OM2 environment (created from this repo's spack.yaml):

==> Error: concretization failed for the following reasons:

   1. No valid value for variant 'deterministic' of package 'access-om2'

Steps to reproduce the error:

git clone https://github.com/ACCESS-NRI/ACCESS-OM2.git
spack env create myenv ACCESS-OM2/spack.yaml
spack env activate -p myenv
spack concretize -f

If you've made modifications to spack.yaml, you'll need to do spack concretize -f --fresh.

Otherwise, it's when the compiler isn't found.

I am only doing the steps listed in "Steps to reproduce the error:" above (after following the spack setup).
If we put that in the instructions we have to make sure it will not generate the same error for the users.

@atteggiani used spack concretize -f --fresh and it worked.
