Every 6 months the Ubuntu Kernel Team is tasked to pick the kernel to be used in the next release. This is a difficult thing to do because we don’t definitively know what will be going into the upstream kernel over the next 6 months nor the quality of that kernel. We look at the Ubuntu release schedule and how that will line up with the upstream kernel releases. We talk to hardware vendors about when they will be landing their changes upstream and what they would prefer as the Ubuntu kernel version. We talk to major cloud vendors and ask them what they would like. We speak to large consumers of Ubuntu to solicit their opinion. We look at what will be the next upstream stable kernel. We get input from members of the Canonical product strategy team. Taking all of that into account we are tentatively planning to converge on 4.15 for the Bionic Beaver 18.04 LTS release.
On the road to 18.04 we have a 4.14 based kernel in the kernel team’s unstable ppa.
