Steps to reproduce the issue

Any of the above result in the same error:

$ spack spec -I libyogrt
$ spack spec -I scr # SCR depends on libyogrt
$ spack spec -I axom # axom depends on SCR
$ spack spec -I macsio # macsio depends on SCR
...

Error Message

--------------------------------
==> Error: invalid values for variant "scheduler" in package "libyogrt": ['lsf']

I imagine this is because

references an invalid value of the 'scheduler` variant:

Adding lsf to the possible values for scheduler fixes the issue, but I am not sure that this fix is correct.
