I inadvertently updated my Linux kernel to version 4.2.0-30 from 3.19.0-33 and it has broken my WiFi and USB drivers, is there a way for me to downgrade my kernel using some sort of cached version?

Run sudo apt-get purge linux-image-4.2.0-30-generic in terminal to remove the new 4.2 kernel.Then reboot
WARNING : If you have removed your old kernel using apt-get or synaptic this can result in an unbootable computer

You really do not need to do this right now when booting ...
- get to the grub menu when booting
- select the previous kernel
- run it
at this point see if the WiFi and USB work If so THEN you can remove the kernel if it bothers you

This is what I also do. However, I use Linux on my home PC and grub automatically loads the latest kernel and my PC boots up my session automatically. That's why it is better to roll back to an older kernel is the best for a person like me. Jan 11, 2018 at 20:22
