repo13 doesn't have any cached lfs files and its source never pushed its
files.  Therefore, the files don't exist in the remote store.  Use the files in
the user cache.

If the source repo doesn't have the blob (maybe it was pulled or cloned with

remote store.

lfs -> normal -> lfs round trip conversions are possible.  The 'none()'
predicate on the command line will override whatever is configured globally and
locally, and ensures everything converts to a regular file.  For lfs -> normal,
there's no 'lfs' destination repo requirement.  For normal -> lfs, there is.
