如何修复＆＃34; apt-get update＆＃34;无效签名错误？

Question

每当我尝试sudo apt-get update时，我都会收到这些错误：

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://packages.linuxmint.com rafaela Release: The following signatures were invalid: BADSIG 3EE67F3D0FF405B2 Clement Lefebvre (Linux Mint Package Repository v1) <root@linuxmint.com>

W: GPG error: http://extra.linuxmint.com rafaela Release: The following signatures were invalid: BADSIG 3EE67F3D0FF405B2 Clement Lefebvre (Linux Mint Package Repository v1) <root@linuxmint.com>
W: Failed to fetch http://packages.linuxmint.com/dists/rafaela/Release  

W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/Release  Unable to find expected entry 'restricted/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)

W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/main/binary-amd64/Packages  Hash Sum mismatch

W: Some index files failed to download. They have been ignored, or old ones used instead.

所以，我做了一些阅读并尝试在sofetware-sources区域更换镜像，并且也遵循这个answer，然后运行这个命令：

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 3EE67F3D0FF405B2

但得到的结果并没有帮助我：

Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.joWxQNcMmd --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --recv-keys --keyserver keyserver.ubuntu.com 3EE67F3D0FF405B2
gpg: requesting key 0FF405B2 from hkp server keyserver.ubuntu.com
gpg: key 0FF405B2: "Clement Lefebvre (Linux Mint Package Repository v1) <root@linuxmint.com>" not changed
gpg: Total number processed: 1
gpg:              unchanged: 1

知道我还能尝试什么来解决它？

p.s这一切都是在尝试安装nodejs和npm时开始的。

Answer 1

这适用于Linux Mint 17 Qiana：

sudo rm -r / var / lib / apt / lists

sudo mkdir -p / var / lib / apt / lists / partial

sudo apt-get clean

sudo apt-get update

sudo apt-key list | grep过期了

  

从该结果中获取密钥：
  pub 4096R / BE1DB1F1 2011-03-29 [已过期：2014-03-28]

sudo apt-key adv --recv-keys --keyserver keys.gnupg.net BE1DB1F1

sudo apt-get update

解决方案部分来自this post。

Answer 2

修复BADSIG错误

应该是packages.linuxmint.com而不是extra.linuxmint.com。

查找哪些包列表文件包含违规主机：

grep -R extra.linuxmint.com /etc/apt/sources.list.d

更改任何匹配的行。

仅供参考，我的一行是/etc/apt/sources.list.d/official-package-repositories.list，现在是：

deb http://extra.linuxmint.com rafaela main

如果您仍有Hash Sum mismatch个错误，请按照社交步骤进行操作。
