If you have problems with copying, deleting or moving files in your Ubuntu folders, you have limited access permissions for file operations in certain folder. Even you are administrator on your Linux system, Linux is double protected, so some files and folders from higher hierarchy are restricted and cannot be changed if you don’t have root permissions. Here is easy tutorial how to get root access:

For example when you install Vuze on your Ubuntu system (check this DetectorPRO tutorial) – if there is any feature updates Vuze will give you an error message about limited access on certain folder, in this case (/usr/share/vuze)

1. For changing that, press Alt+F2 and enter “gksudo nautilus” without quotes. This will start nautilus – default window manager with root access. Now be careful, you can delete any file on your system and your Ubuntu machine can be broken.
2. Next, go to your Linux file system
3. Find the folder that you want to change in this case choose usr/share/ and find vuze
4. right click on vuze folder and choose properties
5. Next, on on tab permissions choose: On all Folder access – create and delete files
6. Click Apply and close the window

Now you can update Vuze to the latest version.

This tutorial can be used for any Ubuntu folder and file in the system. But, again, if you don’t know what you are doing don’t change permissions to system files and folders!
