Default kernel grub

[InvisibleRasta]

Hello, why when installing the lts kernel grub makes it the default kernel in the configuration? how can I make the default kernel the normal linux package?

Grub or gummiboot?

If you use grub, then you can add the following line to /etc/default/grub:

GRUB_TOP_LEVEL=/boot/vmlinuz-linux

and run

grub-mkconfig -o /boot/grub/grub.cfg

and reboot to see the result.

why when installing the lts kernel grub makes it the default kernel in the configuration?

By default, grub-mkconfig sorts the included kernels using sort -V and uses the first kernel in that list as the top-level entry. This means that, for example, since /boot/vmlinuz-linux-lts is sorted before /boot/vmlinuz-linux, if you have both linux-lts and linux installed, the LTS kernel will be the top-level menu entry, which may not be desirable. This can be overridden by specifying GRUB_TOP_LEVEL="path_to_kernel" in /etc/default/grub. For example, to make the regular kernel be the top-level menu entry, you can use GRUB_TOP_LEVEL="/boot/vmlinuz-linux".

GRUB_TOP_LEVEL=“/boot/vmlinuz-linux”

allright thank you. I also have an error when running grub-mkconfig. I dont understand very well what it is about. It seems it cant mount a partition?

The error looks like this one:

GRUB os-prober error

Hey, I ran grub-mkconfig and it shows an error, even though I think it’s probably ok… or is it ? $ sudo grub-mkconfig -o /boot/grub/grub.cfg Generating grub configuration file ...

You can disable os-prober if you don’t need to add other operating system to your Grub.
Or do as the person in that thread and wait until the problem is solved from developers.
