Installation issue: Paraview---"Spack concretizer internal error" inside spack environment about spack HOT 2 CLOSED

Thank you @kwryankrattiger! I could resolve this issue by modifying your solution in the following attributes:

providers:
  # force openmpi as the mpi provider
     mpi: [openmpi]

and

    cuda:
      require: ['11.7:', ~allow-unsupported-compilers]

Ran into other issues later, which I can now say are different from this topic, so I will mark this topic as closed.

What is happening is you are actually specifying two variants of ParaView with unify: true. The first is the one listed in the environment, the second is the one is on the command line.

Instead of installing ParaView from the command line with all of those packages and variants listed on the command line, put all of those in the spack.yaml as the list of specs/packages.

spack:
  packages:
    all:
      providers:
        # force openmpi as the mpi provider
        mpi:: [openmpi]
    paraview:
      require: [+cuda cuda_arch=70, +adios2 +hdf5 +qt +python]
    libfabric:
      require: [@1.15.1, fabrics=sockets,tcp,udp,verbs,mlx]
    ucx:
      require: [@1.13.0, +cma +dc +ib_hw_tm +mlx5_dv +optimizations +rc +rdmacm +ucg +ud +verbs]
    openmpi:
      require: [@4.1.4, fabrics=ucx,hcoll,ofi]
    cuda:
      require: [@11.7:, ~allow-unsupported-compilers]
  specs:
  - cmake
  - paraview

And then concretize the environment like it told you to.

spack concretize -f
