Steps to reproduce the issue

$ spack spec paraview
...
Concretized
--------------------------------
==> Error: invalid values for variant "cuda_arch" in package "paraview": ['10']

Same error when I select the cuda variant and appropriate architecture for my machine.

$ spack spec paraview+cuda cuda_arch=pascal
...
Concretized
--------------------------------
==> Error: invalid values for variant "cuda_arch" in package "paraview": ['10']

What does the "['10']" at the end of the error message mean? It seems that should help me debug the issue.

I don't think I have a build log since fails on 'spec'.
