Why is it that Ubuntu only support a version for a limited time? Since I have been on this site I have seen many references to particular versions not being supported. What does it actually mean? After this time must a user just use the OS in the state it is in at the date that support ends? Does this mean no more package updates are available?
Or when this support date has elapsed, should the user then abandon the version and install a newer version instead? I am slightly confused with the difference between Ubuntu and Linux here (with Windows you use it until you buy the latest version) and would be grateful if someone could explain the Ubuntu 'lifecycle' (if that is a suitable word).
Thanks in advance for your help.
