What is an "end of life" Ubuntu version?
All Ubuntu versions have a life span. Once their time is up they are no longer supported by Canonical or eligible for support on Ask Ubuntu.
There are two types of Ubuntu releases, a short term support release every six months and a long term support (LTS) release every two years.
A short term support release is supported for nine months from the day it was released and a long term support release is supported for five years. At the end of the support period the release is refereed to as end of life (EoL) and no longer supported, no updates, no security patches and no support here.
Please see What's the difference between a Long Term Support Release and a Normal Release? for more information on the different release types.

What should you do if you are using an end of life release?
If you are using an unsupported release, you should upgrade to or install a supported one, as your system is likely to become unstable and insecure. Here are some questions that can help you to upgrade to a supported version:
How do I upgrade to a newer version of Ubuntu?
