[Debian] Apt-get : NO_PUBKEY / GPG error





Issue


When updating the Debian based system, it may happens that the apt-get displays an error message like:


W: GPG error: ftp://ftp.debian.org/ testing Release: 
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 010908312D230C5F

W: There is no public key available for the following key IDs:
010908312D230C5F


This is a new feature of the apt-get system that guarantee the authenticity of servers for updating Debian.

Solution


Simply type the following commands, taking care to replace the number of the key that displayed in the error message:
gpg --keyserver pgpkeys.mit.edu --recv-key  010908312D230C5F
gpg -a --export 010908312D230C5F | sudo apt-key add -
