我正在运行 ubuntu ( focal 20.04) WSL2，并尝试安装 gcc，似乎我需要apt-get update先运行。
我一直收到Could not resolve us.us.archive.ubuntu.com（以下错误）。
我已查找解决方案并编辑/etc/resolv.conf添加其他名称服务器，如下所示：
/etc/resolv.conf
# This file was automatically generated by WSL. To stop automatic generation of this file, add the foll>
# [network]
# generateResolvConf = false
nameserver 172.17.96.1
nameserver 8.8.8.8
nameserver 8.8.4.4

我不知道为什么会这样us.us.archive.ubuntu.com，或者在哪个文件中寻找要更改的设置，如果可以的话。

我通过编辑文件解决了这个问题/etc/apt/sources.list。所有网址都是us.us.archive.ubuntu.com/...，我将其更改为us.archive.com
之后一切都进展顺利。
