Everything has an ending, and that end has reached the Linux Kernel 4.20 life cycle, a version that was released on December 23 last year. As with every new release, v4.20 arrived with important improvements, but reaching the end of its life cycle means that there will no longer be any new changes, which can leave us exposed to new security flaws that are discovered from now on .
And now that? Greg Kroah-Hartman has announced the Linux Kernel 4.20.17 release, which will be the last version for the 4.20 series. Greg recommends updating all users on this version of the Linux kernel as soon as possible. His recommendation is that we update to v5.0.x which has been available for a few weeks. The best thing for Ubuntu users planning to upgrade to Disco Dingo is that we have a little patience.
Greg Kroah-Hartman recommends upgrading to Linux Kernel 5.
Ubuntu 19.04 will arrive with Linux Kernel 5.0 in what seems to be its most outstanding novelty along with the new versions of the different graphic environments and their applications. If you are in a previous version and do not plan to update, you can update the Kernel in different ways, among which using Ukuu stands out for its ease of use. For more advanced users, the different kernels are available in this link.
What version to install? There are three main options: the first is to upgrade to version 5.0. It has already received a couple of stable updates and should offer more fixes than problems. If we want to play it safe, it is best to install a LTS version, among which v4.19 is recommended. The third option is to update to the latest supported version of the 4.20 series, the Linux Kernel 4.20.17 which, if you haven't already, should appear as an update in the next few days. In any case, you have to make sure to keep the kernel up to date.
