本文介绍了解决在Ubuntu系统中因缺少公钥而导致的apt-get更新失败的问题。通过使用gpg命令从pgpkeys.mit.edu获取并导入缺失的公钥，最终成功更新了软件源。

近期要在ubuntu上配置一个代理客户端，需要在/etc/apt/sources.list中添加一个deb源，但是在执行apt-get update时显示“由于没有公钥，无法验证下列签名：NO_PUBKEY 6DA746A05F00FA99

”，其实很简单，只需要下载对应的公钥就可以啦，但是问题就在于一直没有找到一个能下载公钥的网站，好不容易找到一个，记录下来，方便大家以后使用。

解决方法:

$ gpg --keyserver pgpkeys.mit.edu --recv-key 6DA746A05F00FA99
(注意：6DA746A05F00FA99根据你的提示换成你自己所缺少签名对应的公钥; pgpkeys.mit.edu即为网址，好东西啊，必须留着) 

$ gpg -a --export  6DA746A05F00FA99 | sudo apt-key add -
$ sudo apt-get update
