If it ain't broke , don't fix it. Is good advice.
Have you ever heard of phased updates? This explains it.
https://wiki.ubuntu.com/PhasedUpdates
I have 2 installs of 16.04 development version on the same machine and they both have a different kernel version. It is strange but true.
Giving an entirely new version of any widely used software program to our entire user base all at once is unnecessarily fraught with peril.
Instead, let's employ a phased update strategy wherein we provide the updated software to an ever-expanding set of random users. This pool of users will be grown as our confidence of that software update grows, fed by realtime information from the crash database and other potential sources.
This process will be developed in tandem with the efforts to increase testing of packages in -proposed so that we have more confidence in the updates we are pushing out. This process will add to that the ability to pull an update before a large number of users encounter it.
If a kernel upgrade seems to break the system we can go into Advanced options for Ubuntu at the Grub boot menu and select an previous kernel. And then there might be an update a few days later that fixes the problem. There is no need to remove the new kernel.
If you run
Code:
sudo apt-get update
sudo apt-get upgrade
You may see a list of packages being held back. It may include a kernel upgrade. These packages are held back for a reason but they will be installed eventually.
