 |
|
Hello,
I am currently on the stable 6.12.21 amd64 kernel, and I want to upgrade to the unstable 6.14.3 amd64 kernel to test it out.
https://packages.gentoo.org/packages/sys-kernel/gentoo-sources
How do I do this? I have yet to find a comprehensive guide. I'm still new to Gentoo, so I want to make sure I learn this correctly.
Thanks! |

Thanks! That's helpful. I have it installed and symlinked, but my grub is not finding it when I do | Code: | | sudo grub-mkconfig -o /boot/grub/grub.cfg |
Here is the output:
| Code: | james@gentoo ~ $ ls -l /usr/src
total 12
lrwxrwxrwx 1 root root 19 Apr 25 11:28 linux -> linux-6.14.3-gentoo
drwxr-xr-x 27 root root 4096 Apr 25 08:49 linux-6.12.21-gentoo
drwxr-xr-x 26 root root 4096 Apr 10 12:20 linux-6.12.21-gentoo-dist
drwxr-xr-x 27 root root 4096 Apr 25 11:21 linux-6.14.3-gentoo
james@gentoo ~ $ eselect kernel list
Available kernel symlink targets:
[1] linux-6.12.21-gentoo
[2] linux-6.12.21-gentoo-dist
[3] linux-6.14.3-gentoo * |
Then I run grub mkconfig
| Code: | james@gentoo ~ $ sudo grub-mkconfig -o /boot/grub/grub.cfg

I've done some research online about this, but I'm not sure how to rectify this. |

It looks like you have not copied your new kernel to /boot with "make install"; so grub-mkconfig finds only your old kernel. Please read also my comment below the CheatSheet. Please dont do a symlink - you must copy the kernel to /boot.
