SketchBook is not available for Linux but there are some alternatives that runs on Linux with similar functionality. The best Linux alternative is Krita, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 50 alternatives to SketchBook and ten of them are available for Linux so hopefully you can find a suitable replacement. Other interesting Linux alternatives to SketchBook are MyPaint, FireAlpaca, HEAVYPAINT and Gimp Paint Studio.
