This appears to be a Catch-22. If you have the N800 with the Bora system, you do not have libxau0 and cannot install any programs that require it. Several people have suggested that we try to install other programs that already use libxau0 and that will solve the problem ... except those programs cannot be installed. They are mistral programs in mistral repositories and when you try to install them on your n800, they say that they are not able to be installed; they are incompatible. Does anyone actually have an idea that works - someone using an n800 with the updated Bora System, not an n770?
