If you are stumped by a problem, the chances are that someone else has encountered it too. Take a look at our Documentation site where you'll find the official documentation developed and maintained by the Ubuntu Documentation Team.
A range of free support options are also available from the Kubuntu Community, including forums, IRC channel and mailing list. There is also multi-language community support. More information can be found in our Community page.
You can also add your support question in the tech answers system which is a part of the Launchpad system. Here you can keep your query active until a community member offers an answer which solves your problem. You can also search through all of the other questions which have been asked and answered.
