I'm currently running lubuntu 16.04 and recently I updated the kernel from 4.4.0-51 to 4.4.0-75 and upon my next boot lost wifi and hfsplus support. I was able to use grub to use my older kernel, but I'd like to avoid scenarios like this in the future if I can. I'll break my question into four specific parts:
What changes can I make to the Software Updater program to avoid receiving potentially system breaking updates (settings, repos, etc.)?
In the event that a problematic update still gets through that prevents system boot what is the easiest way to get the system back to a bootable state aside from using a full system backup or using grub to load an older kernel?
After restabilizing the system, how can I uninstall/rollback that update from Software Updater?
How can I prevent that update from appearing again as an installable update in Software Updater?
