Kernel upgrades and Linux Kernel headers for development

Post by andyf » Mon Oct 22, 2018 3:45 pm

I'm on Mint Sonya 18.2 and I'm wary of the 4.15 series of kernel updates because of the number of problems I've heard of which are attributed to 4.15.

Consequently, I hide those updates. However, I've noticed that there is often (always?) an update for Linux Kernel Headers for development that is released at the same time. I have been in the habit of accepting these headers updates.

I'm wondering if I've been making a mistake - should I also have been hiding the (seemingly) associated updates for the Headers?

Kernel headers are user for compiling kernel modules. Like for certain graphics card drivers and virtual machine software. If you don't use that, it doesn't really matter.

Thanks xenopeek,

I rarely attempt to compile anything and I don't currently have a VM setup.

However, it is quite possible I will do so in the future. If and when that time comes, is there anything I should do?

It's important that you're using either kernel 4.4 or kernel 4.15. Any other versions are no longer supported on Linux Mint 18.x (Ubuntu 16.04). Which kernel are you on? Personally I'd just install 4.15.

Hi xenopeek,

uname -r says 4.13.0-45-generic

Going back to 4.4 doesn't look like a good choice - or was that a typo for 4.14?

I'd consider a move to 4.14 if you think it would be a good move (no blame).

Neither 4.13 or 4.14 are supported. You have to downgrade to 4.4 or upgrade to 4.15. Those are your two choices for staying safe.

Just upgrade to 4.15. If there are problems with it (I doubt it) you can always boot your previous kernel from the boot menu.
