Quando executo sudo apt-get update , tenho a seguinte saída:

W: GPG error: http://www.debian-multimedia.org squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 07DC563D1F41B907

Eu vasculhei a web, mas só consigo encontrar soluções esotéricas que não consigo entender.

Existe uma maneira de contornar o recurso de segurança que o bloqueia sem entrar na linha de comando esotérica?

    

Answer 1

Como você pode encontrar na página inicial do Debian Multimedia

The first package to install is debian-multimedia-keyring.

Since Squeeze you can install this package with apt-get but you need to press Y when the package ask what to do and do not press return.

Então, resumindo, não se preocupe com apt-get update warning, instale o pacote nomeado e responda Y quando solicitado.
