Ubuntu – How does Canonical choose Linux kernel version for Ubuntu

16.04canonicalkernel

I have Ubuntu 16.04.4 LTS and the Linux kernel version is 4.13.0-39. But in The Linux Kernel Archives I can't find version 4.13.

Edit 1:
How do they choose what Linux kernel version to put in the next point release of LTS version with LTS Enablement Stack?

Edit 2:
What are the criterias to pick a Linux kernel version and put in a Ubuntu version?

LTS enablement stack bring new Linux kernel version along with a point release, but wouldn't that bring the "bugs" from the recently released version?

By default, Ubuntu systems run with the Ubuntu kernels provided by the Ubuntu repositories. However it is handy to be able to test with unmodified upstream kernels to help locate problems in the Ubuntu kernel patches, or to confirm that upstream has fixed a specific issue. To this end we now offer select upstream kernel builds. These kernels are made from unmodified kernel source but using the Ubuntu kernel configuration files. These are then packaged as Ubuntu .deb files for simple installation.
These kernels are not supported and are not appropriate for production use.

See https://wiki.ubuntu.com/Kernel/MainlineBuilds and http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D for more details.

Ubuntu – How to remove Kernel/LTS Enablement Stack

Important: The below instructions only work if you have one of the pre-enablement stack kernels installed still, e.g. 3.2.0-38.

With the Enablement Stack installed run 'uname -r' to check the current kernel version. Substitute it into the command below:

sudo apt-get purge linux-generic-lts-quantal xserver-xorg-lts-quantal linux-headers-generic-lts-quantal linux-image-generic-lts-quantal linux-image-3.5.0-25-generic linux-headers-3.5.0-25

Re-install important components (including X itself!) that are removed due to dependencies by the above commands:

sudo apt-get install xserver-xorg xserver-xorg-input-synaptics

Fix the steam client:

sudo apt-get install libgl1-mesa-glx:i386

Finally, reboot your computer.

IMHO the enablement stack isn't ready for release. In my experience Virtualbox, Samba, and the Steam client all break with the Enablement Stack installed. There's a workaround for Virtualbox but none for Samba or Steam so far (March 2013).

Ubuntu – How To Fix My Kernel Version

My system crashed in the middle of an upgrade and after reboot my kernel was hosed. Because i'm lazy, I remember boot repair which i've used in the past to fix grub, it has an option to repair the kernel.

Boot from live cd and:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair
boot-repair
