In order to use our products/solutions, users shall register with us by becoming our members or contacting us. For pricing information, users can contact us and specify the products/solutions they are interested for price quote. Currently we use Ubuntu as our Linux distro. If users have to use other ones, they shall let us know. Users may want to download and use the newer or latest Ubuntu versions. They can download them directly from Ubuntu, for instance from https://releases.ubuntu.com/jammy/. We may later contact users to request for the Linux distro change or upgrades, which may not happen though. Violators will be fined or charged. Thanks for cooperation and support!
