Any idea how to fix this?

[adamjstewart]

Possible duplicate of #7901 #7339 #7986 #8059 #8133 #9408. Hopefully one of those issues mentions a workaround that helps!

[lcebaman]

Possible, but the solutions provided do not satisfy our system. We cannot even locate packages.yaml. Is there a cleaner solution?

[adamjstewart]

We cannot even locate packages.yaml.

You can figure out where your packages.yaml contributions come from via:

$ spack config blame packages

Also see https://spack.readthedocs.io/en/latest/configuration.html for additional locations where packages.yaml files can be placed if you don't already have any.

Is there a cleaner solution?

I don't currently know of one, but @scheibelp or @tgamblin might.

@scheibelp @tgamblin if we figure out a reliable way to workaround this, we should add it to https://spack.readthedocs.io/en/latest/known_issues.html until a more permanent solution can be found. This seems to be a common issue.

[scheibelp]

What commit of Spack are you on?

the solutions provided do not satisfy our system.

So for example you cannot build mesa? If so, you could do spack spec vtk+osmesa ^hdf5+hl+mpi ^mesa, which should avoid the concretization issue.

I can't reproduce this issue anymore, both with the original and the new concretizer. Closing for now, but feel free to reopen if I missed something.
