Bought a Netis wireless adapter. It comes with quick install directions that only covers WINDOWS although the driver CD has a Linux driver. Tried to install the driver (which was zipped) and was told that I didn't have sufficient permissions to extract the file. I am the only user and the administrator for the computer. How do I get to the Ubuntu 12.04 permission screen to put in my password and gain authorization?
Sometimes the Archive Manager, when invoked within the GUI, prevents extraction of archives that can be extracted in a terminal window using "sudo tar" followed by the appropriate tar options and filename. sudo allows you to supply your password (to authorize an operation) before it is done.
