然后试着用以下指令

1 sudo rm /var/lib/apt/lists/* -vf
2 sudo apt-get update

具体解决：
run these two commands and it should get you fixed up.
Code:
sudo rm /var/lib/apt/lists/* -vf
The first command will remove the damaged list and when you run the second command it will replace it with a new list.

Code:
sudo apt-get update

然后突然想到前天被矿机坑过，我把tmp 文件夹给删了
重新新建了tmp 文件夹后，再试试

结果好了一点儿，现在证书又有问题了。。。。。。。。。。。。。

其实这个是由于新建的 tmp 文件夹权限不够的原因

chmod 777 /tmp

apt-get update --allow-unauthenticated
