This title is misleading.<p>The article is a post on a bulletin board by someone stating two facts:<p>a. Canonical &quot;claims&quot; they provide Long Term Support
b. That support is for the &quot;Main&quot; repository only.<p>Neither of these points is incorrect: though &quot;claim&quot; clearly implies their opinion. All the Linux distributions need to draw the line somewhere on what software they will provide security for: Ubuntu comes from the Debian tradition which packages a large swathe of software, so to differentiate levels of support&#x2F;origin they are separated into repositories. Other distributions reduce the total amount of packaged software made available, to deal with the same issue.<p>The title is misleading because it implies that Ubuntu LTS&#x27; security record is poor: which this article is not discussing.
