Running Ubuntu 14.04.5 LTS on an Acer C720 laptop. Had a mysql database problem due to a system clock error (!). I have tried to remove bluecherry so that I can reinstall, but neither process will complete without errors. Here's the removal attempt. What am I doing wrong? Do I have to reinstall ubuntu completely?
