bleachbit error


Hello, I have a problem with root application. In my point of view I can see the following.
"Off topic: Failed to run bleachbit as user root.Unable to copy the user's Xauthorization file."
With the support of ubuntu community support
the problem was limited to the opening of a small password requesting code.
Applying input to the correct code was not opened.
What to do ;

BleachBit version: 
Your operating system: 
ubuntu 17.10

Does this solution help? It has to do with the permissions for the Xauthority file.

“Unable to copy the user's Xauthorization file”
