System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 528.49

Blender Version
Broken: version: 3.5.0, branch: blender-v3.5-release, commit date: 2023-03-29 02:56, hash: 1be25cfff18b
Worked: No idea.

Short description of error
Blender generates an error when you attempt to enter edit mode on a library overriden armature. There's no description of what the error is or if there is some extra step to make it work. Hopefully this isn't one of those, "works as intended issues," because then there's no way to make multiple characters share an updateable base rig.

Exact steps for others to reproduce the error

Add an armature, enter edit mode, extrude out a few bones.
Save the file and open a new scene.
Link in the armature you just created.
Make the armature a library override.
Try to enter edit mode. Should get an error.

This looks like intended behaviour. Blender does not seem to allow editing an library override.

For now if you want characters to have a shared rig, it should be adequate to make them have the same vertex weight names and arrangement, and adding a same armature structure should carry the movement across.

The lack of explanation of the error message maybe can be improved, but from the way the operator is called, it doesn't seem to be that straightforward.

static bool editmode_toggle_poll(bContext *C)
{
  Object *ob = CTX_data_active_object(C);

  /* Covers liboverrides too. */
  if (ELEM(nullptr, ob, ob->data) || ID_IS_LINKED(ob->data) || ID_IS_OVERRIDE_LIBRARY(ob) ||
      ID_IS_OVERRIDE_LIBRARY(ob->data))
  {
    return false;
  }
