Remove an Old Kernel

Hello,

How would I remove an old kernel that on my computer says it’s no longer installed?

Unable to install module steamos-xpad/20190810 for kernel 4.14.221-1-MANJARO: Missing kernel modules tree.

Please help, thank you!

Hello,

Open up Manjaro Settings Manager > Kernels and you can remove it from there, or check if is installed. Otherwise from Terminal:
sudo mhwd-kernel -r linux414

Is all documented in the Manjaro Kernels - Manjaro wiki …

That’s to remove it!

First install another kernel, for example from the terminal:

sudo mhwd-kerneel -i linux54 

Or

sudo mhwd-kernel -i linux510

(5.4 is the current LTS and 5.10 is set to be the next LTS.)

If successful, you can then remove 4.14:

sudo mhwd-kernel -r 414

Hold your thumbs and reboot.

If all went well, then you’re good to go!

I am already running linux 510 which is the odd part about this.

When I ran

sudo mhwd-kernel -r 414

I got
