Before we get into any details of the upgrade process, we’d like to inform you that Ubuntu 16.10 comes with a newer and more advanced kernel, namely Linux 4.8, as well as up-to-date software components. However, if you’re running the Ubuntu 16.04 LTS (Xenial Xerus) operating system, you shouldn’t upgrade just now. Why? Because Ubuntu 16.10 is a short-term release that will be supported for only 9 months, until July 2017, and Ubuntu 16.04 is a long-term support version that’s more stable and more reliable, and you’ll get software and security updates for the next 5 years, until April 2021.
