The Kubuntu Community was pleased to announce a few minutes ago, September 2, 2013, that professional and commercial support for the Kubuntu Linux operating system is now available for purchase.
The Kubuntu professional support is provided by the WithSupport office in England, and users will be helped via telephone, email, Skype remote desktop login, or any other method chosen by the customer.
Getting commercial support for Kubuntu has been an effort over a year in the making and one that has had its fair share of challenges. "At first we had to fight hard to get Canonical to allow us to use the trademark," Riddell said.
Database Journal: "One of the key elements that helps to enable open source software applications to gain broader enterprise usage is the availability of commercial support options. In the case of the open source MongoDB NoSQL database, that commercial support is now coming from project backer 10gen."
since 12.10 packages like kubuntu-desktop are no longer in main, but
universe. If I remember correctly only main and restricted get LTS support
(I can't find any mention of this on the LTS Ubuntu wiki page, so maybe
things have changed/I am wrong).
