我换了清华的源
apt update时出现了问题:
E: 无法下载 https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/dists/focal/main/binary-i386/Packages 404 Not Found [IP: 101.6.8.193 443]

E: 部分索引文件下载失败。如果忽略它们,那将转而使用旧的索引文件。

对了我的电脑是ARM处理器的所以用了 https://mirror.tuna.tsinghua.edu.cn/help/ubuntu-ports/ 这个源(其他源也试过了不行)

ping了其中一个:
root@TuXg-PC:~# ping 101.6.8.193 443
PING 443 (0.0.1.187) 56(124) bytes of data.

对了我是root的权限

问题补充:

对了,我可以联网
root@TuXg-PC:~# ping baidu.com

可能是装图形化界面弄坏的
