关于apt-get update时遇到签名错误的解决方案, [debian][ubuntu][apt] Options

[猫猫草]

比如安装 VirtualBox 时出现

代码

A error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://download.virtualbox.org karmic Release: The following signatures were invalid: BADSIG 54422A4B98AB5139 Oracle Corporation (VirtualBox archive signing key) <info@virtualbox.org>

这是因为软件索引数据库出错导致的，解决方式如下：

代码

apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update

注意可能需要视情况添加 sudo 等前缀命令

成功后即可 rm -rf /var/lib/apt/list.old 了
