How to upgrade from Ubuntu 14.04.3 to 14.04.4

3 months ago, I installed Ubuntu 14.04.3 with the 3.19 kernel. My current kernel version is 3.19.0-49-generic

Since I have a new DELL Precision 5510 laptop with Intel's Skylake technology, some features only work with the new 4 core

So I was waiting for Ubuntu 14.04.4 with the 4.2 kernel to be released in February 2016: https://wiki.ubuntuusers.de/LTS_Enablement_Stacks/ I read that this was a release a few days ago: 11. Februar 2016

But it seems that this release is not installed automatically with regular system updates. How can I migrate / update this new version without risking some instability.

Thank you and good wishes.

As pointed out by @Larry Greenwald and described here . To update the kernel, you need to do this manually:

$ sudo apt-get install --install-recommends linux-generic-lts-wily

I made several updates in the 14.04.x ​​series. The apt-get dist-upgrade command will update most things, but not necessarily the kernel. "Uname -a" after the update (and subsequent reboot) will tell you.

If you still have the 3.19 series kernel, you can do "sudo apt-get install Linux-generic-lts-wily" to get the 4.2 kernel.
