This is really not new, but it is frustrating that Ubuntu has not been able to fix this over the years. Just reinstalled 18.04 because I was getting graphics driver problems which were preventing me even updating software due to broken dependencies, and what should be an easy restore is driving me crazy. I had problems initially with my earlier installation of 18.04 but it sorted itself out I don't know how. Here is the information gathered from the Ubuntu DebuggingPrintingProblems link:
