我还分别尝试运行了

apt get update

，得到了类似的结果。因此，我四处寻找了一些答案，它似乎与

来源有关
这是我的资料来源。列出目录
deb http://archive.ubuntu.com/ubuntu precise main restricted universe
deb http://archive.ubuntu.com/ubuntu precise-updates main restricted universe
deb http://security.ubuntu.com/ubuntu precise-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu precise partner

My sources.list.d/certbot-certbot-precise.list
deb http://ppa.launchpad.net/certbot/certbot/ubuntu precise main
deb-src http://ppa.launchpad.net/certbot/certbot/ubuntu precise main

我不确定这是否是问题所在，我也不知道我需要在sources.list中更改哪些内容，因此任何建议都将不胜感激
谢谢
