Sorry for skipping the answer. The question mentioned missing library and I did not think that is the same as missing packages. I do not know anything about linux codes. When I see all the coding in the answer, it scare me off. Please be patient with me.

So how do I do with you instruction? I know I have to start the xterm. Do I have to type anything else? Go to a specific place before I enter the command?

Also, do I uninstall the previous veriosn before I enter the command.

Do I backup everything first?
