But imagine having to do this with a GUI, over the phone. I don’t think I would even try...
Well you could try telling someone the following over the phone and they might end up with an empty /var/lib/apt/lists/partial folder... type "control" "alt" "t" in the terminal window type: "gksu nautilus" enter password click on "Computer" double-click on "var" double-click on "lib" double-click on "apt" double-click on "lists" double-click on "partial" move the mouse to the menu bar and click on "Edit" on the drop down menu click on "Select All" right click in the nautilus window to display a menu left click "Move to the Rubbish Bin". close nautilus close the terminal window In summary: 3 keyboard entry's and 12 mouse clicks. ...but you might need to also do a sudo apt-get install gksu
