Kali更新系统，解决：Updating from such a repository can't be done securely, and is therefore disabled by default.

今天想更新下kali版本，新版2021.2有些新功能挺好用的，但是出现了问题。

E: The repository 'http://mirrors.163.com/debian wheezy Release' does not have a Release file.
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.

翻译了一下这句报错，大概意思就是无法安全的更新，看了下源地址都是http的，把源地址改成https的就可以了。

sudo vi /etc/apt/sources.list

#清华大学
deb https://mirrors.tuna.tsinghua.edu.cn/kali kali-rolling main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/kali kali-rolling main contrib non-free

然后更新系统即可

apt update && apt full-upgrade
