Libmesh conda compatibility with old moose

[louisBS]

Hi all,

I updated my libmesh ( using conda update -all) and now I cannot compile my old moose using the latest libmesh. It's a bit of a pain for me to rebase my moose by resolving all the conflicts, so I wonder if there's any way for me to downgrade my libmesh version using conda to what it was before ?

Thank you very much,
Louis

I believe you can use conda search -i moose-libmesh to find the available versions of libmesh for moose and then use conda install moose-libmesh=<ver> to install a specific version (i.e. moose-libmesh=2021.02.15 to roll back one version). This should also roll back any dependencies like moose-petsc to their correct versions as well, but there may be other packages that you may also need to roll back separately.
