May be some explanation on when this happened. I was experiencing a loss of GPG PUBKEYs as described by "Apt-get Reports NO_PUBKEY GPG Error for Keys that are Present in Trusted"
https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1263540 Then I ran : $ sudo apt-get install ubuntu-keyring --reinstall This caused a crash while re-installing the ubuntu-keyring package. Later I did proceed as explained by the latest posts on bug 1263540. I deleted all the contents in /etc/apt/trusted.gpg.d/ (Not exactly) : $ sudo mv /etc/apt/trusted.gpg.d/ /etc/apt/trusted.gpg.d.old/ $ mkdir /etc/apt/trusted.gpg.d/ Then I ran : $ sudo dpkg -i webupd8/launchpad-getkeys_0.3.3-1~webupd8~2_all.deb (launchpad-getkeys was found here : http://www.webupd8.org/2010/05 /automatically-import-all-missing.html) $ sudo launchpad-getkeys $ sudo apt-get update ... This solved the issue for me. Still the ubuntu-keyring is not broken and performing well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1437209 Title: package ubuntu-keyring 2012.05.19 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-keyring/+bug/1437209/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
