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,并且也遵循了这个answer,并运行了这个命令：

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

但得到的结果对我没有帮助：

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才能解决它？

p.s这一切都是在尝试安装nodejs和npm时开始的.

解决方法

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已过期

Get the key to use from that result:
pub 4096R/BE1DB1F1 2011-03-29 [expired: 2014-03-28]

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

sudo apt-get update
