[Solved] "/bin/rm: cannot remove `/run/user/root/gvfs': Is a directory" When exit from root / superuser

This problem occurs when we have entered in the root or superuser, then when trying to exit, show this information "/bin/rm: cannot remove '/run/user/root/gvfs': Is a directory" like image below:

So, how can fix this?

1. Open your Terminal by press Ctrl+Alt+T
2. Then type this following command: sudo umount /run/user/root/gvfs
3. So, after you exit from superuser, you will not see this information again.
