Troubles with Packing

I am trying to pack some blender files and running into a little confusion…I linked a file whose linkage had been disturbed, Saved the .blend file but when I selected “Pack,” I get a message saying “No Blend files have been packed.”

Anyone know what that even means and/or what the remedy would be?

It would be nice if it said why no files had been packed, but…no such luck…:eyebrowlift:

thank you for any clues about this.
