问题 apt命令报证书错误

Certificate verification failed: The certificate is NOT trusted

处理办法

1.更改源文件，将所有的https改成http：

sudo vi /etc/apt/sources.list

更改过后如下：

deb http://mirrors.zju.edu.cn/ubuntu/ focal main restricted universe multiverse
deb http://mirrors.zju.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb http://mirrors.zju.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb http://mirrors.zju.edu.cn/ubuntu/ focal-security main restricted universe multiverse

2.更新源

sudo apt-get update

3.安装/更新证书ca-certificates

sudo apt-get install --reinstall ca-certificates

4.参照步骤一将镜像源文件改回https
改完后/etc/apt/sources.list 文件内容如下：

deb https://mirrors.zju.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.zju.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.zju.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb https://mirrors.zju.edu.cn/ubuntu/ focal-security main restricted universe multiverse

5.再次更新源

sudo apt-get update

6.至此可以正常安装软件了。

sudo apt-get install xxxxx
