debian-keyring, ubuntu-keyring, gnome-keyring
I had some problem with keyring packages during distro upgrade process.
I assume that these packages have something to do with security.
I also get advices to use lines like below to solve my problems.
gpg --keyserver wwwkeys.eu.pgp.net --recv-keys 40976EAF437D05B5
gpg --armor --export 40976EAF437D05B5 | sudo apt-key add -
Can anybody here explain me please how the whole system of xxx-keyrings packages working? Or just point me somewhere where is some good HOW-TO.
I would like to more understand this.
Thanks in advance
