我有一台在 Debian Wheezy 上运行的服务器。
它的 apt 源文件具有以下配置：
deb http://ftp.uk.debian.org/debian/ wheezy main non-free contrib
deb-src http://ftp.uk.debian.org/debian/ wheezy main non-free contrib
deb http://security.debian.org/ wheezy/updates main contrib non-free
deb-src http://security.debian.org/ wheezy/updates main contrib non-free
# wheezy-updates, previously known as 'volatile'
deb http://ftp.uk.debian.org/debian/ wheezy-updates main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ wheezy-updates main contrib non-free
当我尝试更新时，我收到官方 Debian 存储库的 GPG 错误：
root@osgb:~# apt-get clean
root@osgb:~# apt-get update
