What is going on and how do I fix it?

Question

I'm trying to get onto the xfce4 client from my chromebook (and it has worked before), however now this error is popping up. How do I fix this error?

My guess is you may not have the right user privileges. According to the error message you provided you are running an Ubuntu Linux environment.

If you haven't tried running the program through the terminal yet, attempt to do so.
The terminal can typically be opened by the key combination Ctrl+Alt+T on ubuntu linux.

Try using sudo command before running the program. This will run the command you enter using root privileges.

For example, if running the program on your terminal is

myName@ubuntu: xfce4 

And this encounters an error, try to use sudo beforehand like so:

myName@ubuntu: sudo xfce4 

Alternatively you can log in and not have to type sudo before every command.

myName@ubuntu: sudo bash
password:

If this fails you may need to update the package that contains the library. This can be done on the terminal in a fashion similar to:

myName@ubuntu: sudo apt-get install --only-upgrade xfce4
