I hope this is just a joke, because the kernel.org says about this kernel version: "longterm / 2.6.32.68 / 2015-09-18", and the changelog (which I check as I wrote this sentence) has many changes made very recently. Most of remote machines I'm using right now have Ubuntu installed on them. The newer Ubuntu releases have suffered, always with things that use to work since years before... and suddenly (or magically) someone do something to make them break. I prefer relatively old things - that work, and there are many! It is usually easier to work with things that are known to many people and for a long time than recent nice changes that sometimes have new surprises. And I checked one detail: Welcome to "Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-61-generic x86_64)"; this is what I see when I log into one of the remote machines. If Ubuntu is using 3.13 kernels I won't even bother trying the 4.x+ ones. I prefer a linux with a kernel like those that were used in machines that stayed up for years, without any big changes on them (just configuration files, rarely, and nothing else). We see so many people with top-notch mobiles and tables that sometimes suffer to do basic things we have done for decades, like sending email... that's no good technology, I don't want to be too close to these. :) Anyway, lets stop talking nonsense... hehehehe > > Steps done: > > > > 1. downloaded https://cdn. kernel > > .org/pub/linux/kernel/v2.6/longterm/v2.6.32/linux-2.6.32.68.tar.xz > > 2. extract with tar cJf (whatever) > > 3.
