The problem however is that when I try to install a new package or upgrade an existed one, using the apt-get install command, I get a question asking me: 'Install these packages without verification?' and above this questionis a list of some packages that cannot be verified. so my question is why does some packages cannot be verified and how to solve this trouble?
apt-cache show debian-archive-keyring
What's your meaning? this package is already installed on my machine but the problem is still existed.
