当我尝试时apt-get update它说：
Get:1 http://archive-3.kali.org/kali kali-rolling InRelease [30.5 kB] Err:1 http://archive-3.kali.org/kali kali-rolling InRelease The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <[email protected]> Reading package lists... Done W: GPG error: http://archive-3.kali.org/kali kali-rolling InRelease: The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <[email protected]> E: The repository 'http://http.kali.org/kali kali-rolling InRelease' is not signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.
我的/etc/apt/source.list看起来像这样：
deb http://http.kali.org/kali kali-rolling main contrib non-free
# For source package access, uncomment the following line
# deb-src http://http.kali.org/kali kali-rolling main contrib non-free
# deb cdrom:[Debian GNU/Linux 2017.3 _Kali-rolling_ - Official Snapshot amd64 L$
#deb cdrom:[Debian GNU/Linux 2017.3 _Kali-rolling_ - Official Snapshot amd64 LI$
我应该怎么办 ？谢谢！

事实上，你的钥匙已经过时了；您需要首先更新您的密钥。尝试一下：wget -q -O - archive.kali.org/archive-key.asc | apt-key add就可以开始了。
