Ubuntu No Pubkey

But when I reload the package database, I get an error like the following: W: GPG error: http://ppa.launchpad.net trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8BAF9A6F I know I can fix it using apt-key in a terminal, according to the official Ubuntu documentation. But I would have liked to do it graphically. gpg error debian Is there a mean not to open a terminal? apt gnupg share|improve this question edited May 11 at 21:10 Mateusz Konieczny 363118 asked Nov 13 '10 at 20:27 Agmenor 5,96484089 Related: askubuntu.com/q/127326/178596 –Wilf Jul 19 '15 at 20:46 'A mean'? 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 4 '13 at 15:52 monotasker 1,6131813 The first reply that actually answers the question properly : how to d

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 once. To add these keys, run the following commands: [chris@server ~]$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5 Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.QTeppiINUh --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5 gpg: requesting key 437D05B5 from hkp server keyserver.ubuntu.com gpg: key 437D05B5: public key "Ubuntu Archive Automatic Signing Key <
