Ubuntu 20.04 Confirms Its Kernel Choice (And Spoiler: It Isn’t the Latest)

Ubuntu 20.04 will ship with Linux 5.four kernel and never the current Linux 5.5 launch.

The choice, confirmed on the Ubuntu kernel mailing list, isn’t precisely a serious shock: Ubuntu 20.04 is the following Lengthy Time period Assist launch of Ubuntu, and Linux 5.4 is the newest Lengthy Time period Assist launch of the Linux kernel.

It’s arguably far much less effort to make use of an LTS Linux kernel in an LTS distro

Each obtain on-going help for a few years — so there’s a long run synergy, if you’ll!

Arguably there’s simply sufficient time between now and the discharge of the ‘Focal Fossa’ for Canonical’s crack crew of kernel devs to arrange, package deal and ship the 5.5 kernel — however Canonical would additionally must decide to help it for 5 years (help from upstream kernel builders ends in just a few months).

So it’s arguably far much less effort — and to not point out much less problem — to make use of an LTS Linux kernel in an LTS distro. Linux 5.four LTS is maintained till 2021 by kernel builders, that means the “patching vital flaws” burden is shared out.

“We’re constructing the Focal / 20.04 LTS kernel based mostly on the upstream 5.four kernel. We’ve a model of this Ubuntu kernel within the -release pocket and continut to iterate and replace it often whereas working in direction of the 20.04 launch date,” writes Canonical’s Brad Figg.

Don’t overlook: people will be capable to improve to newer kernels on Ubuntu 20.04 LTS. The {Hardware} Enablement Stack (HWE) offers back-ported kernels from newer Ubuntu releases to LTS customers, at common intervals.
