The error means that there is some object referenced in your repository 
or the incoming changes that you do not have locally and the server 
either does not have it at all or does not have contained in any public 
branches/tags.

Ensure you've done a git submodule update --init --recursive.

If it persists, try doing a fresh clone.  If the problem goes away, it 
was probably a lost object on your side.

Otherwise, the next most likely cause is that someone has pushed a 
commit referencing a submodule commit that hasn't been pushed, or has 
force-pushed away some commit that you were depending on.  This is very bad.

(It's most likely someone forgetting to push the submodule.  That's a 
very easy mistake to make, especially if they haven't set 
push.recurseSubmodules [1].  The default for that is silly and everybody 
should set it.)
