Kali Linux使用apt-get更新报错密钥过期解决 GPG错误 KEYEXPIRED 1425567400
问题描述
Kali Linux由于太长时间未更新，而出现GPG错误 KEYEXPIRED 1425567400。经检查源未出现问题可以解析，deb也不冲突，就是密钥过期了。
好久没有更新kali了，今天趁着更新了虚拟机，便打开想要跟新一下这个系统，结果没想到遇到了如图的问题。
先是使用GUI来更新出现了404错误，然后使用apt-get则报错密钥过期。
好吧，无论如何，这不是deb冲突，也不是源无法解析，你需要做的是更新密钥。
使用下面的一条命令来将新的密钥添加进你的apt-keyring
apt-key adv --keyserver hkp://keys.gnupg.net --recv-keys 7D8D0BF6
然后在执行 “apt-get update”即可。
这样再次更新软件列表就不会出现GPG错误了，也不会再出现404问题。
我使用内核3.12-Kali-AMD 64运行版本1.0.9 64位，并在尝试使用APT-GET更新时获取错误
首先尝试命令行接口，得到错误。下面是控制台输出，gpg键和源列表。
在过去的两天里，我更新了2台台式机，没有问题。我遇到麻烦的机器是ThinkPad X1碳。
使用软件更新gui会出现“未能处理请求”错误：
