System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 445.75

Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-02-12 16:20, hash: 77d23b0bd7

Short description of error
When you link a collection with a rig (an armature controlling a mesh), and use Make Library Override, you can't control the shapekeys of the mesh from inside the rig with drivers, whereas you can in the original file of the rig, or using a proxy instead of a library override.

While it's true that the command Make Library Override doesn't override the mesh data when you override the Armature, even after you manually override the mesh data, the driver keeps not working. You have to click on each shapekey slider, click edit driver, and then select the other armature, which is named exactly the same as the armature that's being referenced but it's not in the scene. This is tedious if the mesh has many drivers

Exact steps for others to reproduce the error

Create a new file and clear the scene of objects
go to File > Link > this file cubecollection.blend > Collection and link the collection called CubeRIG
Selected the instanced linked collection and go to Object > Relation > Make Library Override, and override the armature
if you go to pose mode and move the bone in the global Y axis, you will see that nothing happens. the cube should deform with a shapekey but it doesn't
if you select the cube mesh, you may go to the mesh properties in the hopes of fixing it by shift+clicking the chain icon and overriding the mesh datablock itself. but moving the bone in pose mode won't work again
at least by overriding the mesh, now you can right click on the purple shapekey slider and select Edit Driver, there you can choose another object for the propery of the variable, select Armature instead of Armature (they're named the same) and now moving the bone in pose mode does work

Unrelated but maybe related bug or missing functionality??

Make Library Override only works with Collection instances and not linked objects directly. One would think it would be easier for the macro but yeah

Looks like this has been reported before, see #70319 (Library Override: Driven Shape Keys Don't Work (neither via custom properties nor transforms)), so will merge these reports, lets continue discussion in #70319...

Unrelated but maybe related bug or missing functionality??

Please only one issue per report, feel free to open another report for this...
