While trying to update my Android SDK I am encountering this error when trying to install this particular package:
Same error i got while updating sdk. It is because of targeted folder locked (access permission is denied). You can resolve it as follows in "Ubuntu" :-
Press ALT + F2 and type 'gksudo nautilus' and navigate to the targeted folder like tools or extras and give create and delete permission. then update, every thing will be working fine :)
