I am Using Ubuntu 18.04.2
I have recently came to know about systemd-boot via https://askubuntu.com/a/1135735/739431

So, I dont have grub in my system. I am Using systemd-boot and happy with it..

I think Ubuntu 18.04.2 ships with Kernel 4.xx.x-xx-generic some version
{ex: linux-headers-4.18.0-17-generic}

to Update kernel I am using the tool UKUU (Ubuntu Kernel Update Utility)

I am updating the Kernel every time when UKUU shows a notification about new Kernel Release like this..

enter image description here

Once I Choose "Install" It runs some commands like this and finally Installs the new Kernel in my System..

enter image description here

My Present Kernel

pratap@i7-4770U:~$ uname -r
5.0.11-050011-generic
pratap@i7-4770U:~$

thoughts:

my imagination is that UKUU tool is running some commands those are shown in above image, and I want to run those commands my self when I want to install specific Kernel Version..

Question:

Is it possible to run the commands manually that UKUU is doing in above Image by uninstalling the tool UKUU and successfully update the kernel? I Can check the latest Kernel Versions available from the website https://www.kernel.org/.

  • You might review [https://www.ostechnix.com/different-ways-to-update-linux-kernel-for-ubuntu/](https://www.ostechnix.com/different-ways-to-update-linux-kernel-for-ubuntu/) and [https://help.ubuntu.com/lts/installation-guide/i386/ch08s06.html](https://help.ubuntu.com/lts/installation-guide/i386/ch08s06.html) – Charles Green May 04 '19 at 14:41
  • @CharlesGreen thanks for the links.. i will go through them.. mean while my main question concentrates on how to catch up commands what ukuu tool is doing and running them manually to successfully update the kernel.. – PRATAP May 04 '19 at 15:10
  • Ukuu is downloading .deb files from [https://kernel.ubuntu.com/~kernel-ppa/mainline/](https://kernel.ubuntu.com/~kernel-ppa/mainline/) and using `apt` or `gdebi` or `dpkg` to do the installation. You will then need to modify grub if you want to run a particular installed kernel - `grub-customizer` might be of help for that. – Charles Green May 04 '19 at 15:19
  • @CharlesGreen seems your comment gave some clue.. if kernel can be installed i can run it.. i am looking for the part upto successful installation only.. i will try with your comment above and thanks for your time on this.. – PRATAP May 04 '19 at 15:23
  • For me, as I run on older hardware, there is very little reason to push the kernel envelope. If your interest is trying to learn more about kernels, I would suggest that you fire up a VM, and compile kernels *in the VM*. I believe it is possible to squeeze more performance out of your system, but maintenance of such a system becomes non-trivial. – Charles Green May 04 '19 at 16:01

I asked a similar question here and the general consensus was that if it ain't broke, don't fix it.

I was particularly impressed with @Rinzwind answer: ignore it ;-) I know it itches :D :D and it took me a year or 2 to accept to just ignore it. – Rinzwind Apr 21 at 17:17 and @heynnemma who advised:

don't manually update it to 5.0.9. If this is a personal machine

  • @PRATAP fair comment but some may go where angles fear to tread encouraged by an answer to your question. – graham May 04 '19 at 16:07
