apt-get

运行apt-get update时经常遇到的问题就行以下问题,导致无法更新或安装软件

秘钥不匹配、密钥找不到、过期、密钥错误、public key等问题。

W: GPG error: http://repo.mysql.com wheezy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8C718D3B5072E1F5

比较简单的解决办法就是:

apt-get install debian-keyring debian-archive-keyring
apt-key update
apt-get upgrade   #此时会重新获取正确的key并提示你确认
