I decided to upgrade to 33 once it came out. Had to remove jfx version 8 as it was conflicting to 11. Then I thought it will be a smooth sail. But after a couple of hours, hit the 64% mark and the system was stuck at the point for 30+ hours without progress. I decided to abort (i know it is not good - but without any visual feedback on what is happening and waiting for 30+ hours, was not sure there was an endless cycle of trying to get some packages and failing). Now my system is not usable. Is there a way to repair this or copy my files and start afresh?
