Case

Currently Ubutun version update iterations too fast ~ Regular version of the maintenance period is relatively short, within a year, only the LTS version will be long-term support for 3-5 years.

But for older versions of Ubuntu that are no longer maintained, the old source is officially available for updating and installing software

Operation Steps:

One

First backup Ubuntu Linux source list (also can not backup, add the new address directly behind)

sudo cp/etc/apt/sources.list/etc/apt/sources.list.backup (back up the current source list, be prepared for it)

Two

Modify/etc/apt/sources.list:

$sudo gedit/etc/apt/sources.list

Three

Replace all source addresses with

Http://old-releases.ubuntu.com/ubuntu, be careful not to delete the later system version and classification.
