If you are running a machine that is vital to workflow, and needs to absolutely never ever ever have any chance of anything going wrong (i.e. a server) then no, don’t install every update. But if you are like most normal users, that are using Ubuntu as a desktop OS, yes, install every update as soon as you get them.
Is Upgrading Ubuntu safe?
Upgrades are normally safe, but there is always a chance something may go wrong. It is crucial that you have your personal files safely copied to a backup location, so you can restore them if there are any problems or complications.
Will upgrading Ubuntu delete my files?
You can upgrade all currently supported versions of Ubuntu (Ubuntu 12.04/14.04/16.04) without losing your installed applications and stored files. Packages should only be removed by the upgrade if they were originally installed as dependencies of other packages, or if they conflict with newly installed packages.
