Curious what you meant by that. –Michael Scheper Sep 13 at 16:17 add a comment| 10 Answers 10 active oldest votes up vote 113 down vote accepted By far the simplest way to handle this now is with Y-PPA-Manager (which now integrates the launchpad-getkeys script with a graphical interface). 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 6,052112957 answered Dec

E: Some packages could not be authenticated [chris@server ~]$ The apt packaging system has a set of trusted keys that determine whether a package can be authenticated and therefore trusted to be installed on the system. Sometimes the system does not have all the keys it needs and runs into this issue. Fortunately, there is a quick fix. Each key that is listed as missing needs to be added to the apt key manager so that it can authenticate the packages. Looking at the error above, apt is telling us that the following keys are missing: 40976EAF437D05B5 and 3B4FE6ACC0B21F32. Notice that these are listed multiple times. Each unique key will only need to be added
