Some users still have issues getting LFS files downloaded properly, though the exact cause is unclear. Normally with a properly installed git lfs, git pull should already take care of it. When for whatever reason that is not the case and files have not been fetched yet, now do lfs pull which is the same as lfs fetch + lfs checkout. Even when git pull can not run.
