To install it, first add the webupd8 repository for this program: sudo add-apt-repository ppa:webupd8team/y-ppa-manager Update your software list and install Y-PPA-Manager: sudo apt-get update sudo apt-get install y-ppa-manager Run y-ppa-manager (i.e. type y-ppa-manager then press enter key). When the main y-ppa-manager window appears, click on "Advanced." From the list of advanced tasks, select "Try to import all missing GPG keys" and click OK. You're done! As the warning dialog says when you start the operation, it may take quite a while (about 2 minutes for me) depending on how many PPA's you have and the speed of your connection. share|improve this answer edited Nov 7 '14 at 21:05 guntbert 6,079112957 answered Dec 4 '13 at 15:52 monotasker 1,6431813 The first reply that actually answer
