Support

There are a couple of different ways that Ubuntu Server Edition is supported, commercial support and community support. The main commercial support (and development funding) is available from Canonical Ltd. They supply reasonably priced support contracts on a per desktop or per server basis. For more information see the Canonical Services page.

Community support is also provided by dedicated individuals, and companies, that wish to make Ubuntu the best distribution possible. Support is provided through multiple mailing lists, IRC channels, forums, blogs, wikis, etc. The large amount of information available can be overwhelming, but a good search engine query can usually provide an answer to your questions. See the Ubuntu Support page for more information.
