Now I realized why it didn't happen in stock Ubuntu: because "ubuntu.noble" was checked out already so "ubuntu.noble/language" directory exists.

However, as for ubuntu-oem, it checks out "ubuntu-oem.noble" but not "ubuntu.noble", therefore "ubuntu.noble/language" does not exist, triggering this issue.
