Utilizing a Custom Kernel on Your Ubuntu VPS
Choose a kernel
Selecting a Kernel from http://mirrors.kernel.org/ubuntu/pool/main/l/linux/[1]. For this tutorial, we choose the latest available version, which is 4.14.0-11-generic.
Install and download
Commands starting with # indicate that you need to run them with root privileges. Depending on your preference, you can use either sudo or su -c.
For 64bit installation:
$ wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux/linux-image-4.14.0-11-generic_4.14.0-11.13_amd64.deb
# dpkg -i linux/linux-image-4.14.0-11-generic_4.14.0-11.13_amd64.deb
For 32bit installation:
$ wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux/linux-image-4.14.0-11-generic_4.14.0-11.13_i386.deb
# dpkg -i linux/linux-image-4.14.0-11-generic_4.14.0-11.13_i386.deb
Note: If a prompt box appears with the message “A new version of /boot/grub/menu.lst is available,” be sure to choose “install the package maintainer’s version.” Failing to do so may prevent you from updating grub.lst automatically.
