I'm lost. I cannot find the answer I need anywhere. I updated to 4.4.0-81 and ever since doing so I cannot access many of my installed software. Nothing happens. No errors coming up. I would like to get back to 4.4.0-77 which worked fine. I made the mistake of purging the functional kernel before testing. I cannot figure out how to roll-back.
My system was stable as can be with the older Kernel. How can I go back?
