I recently ran into the issue described at How to get rid of wrong kernel (-oracle) from Software Updater update. I fixed the issue by booting into a previously-working kernel and purging the oracle kernel.
How can I prevent this happening in the future? i.e. how do I prevent apt from installing another kernel that may break my system?
I know that it's impossible to determine whether a given kernel will break my system or not without actually trying it, but at least disallowing kernels that don't end in -generic seems like a good start. Is there a way to do that?
