今天在WSL进行操作的时候，发现从网络上下载东西无法成功，包括wget
、apt-get 等命令都无法正常使用，比如执行sudo apt-get update
的时候会提示

经过查询和搜索（解决bug真的痛苦😫），发现通过一下几行命令可以解决

| sudo rm /etc/resolv.conf
sudo bash -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf'
sudo bash -c 'echo "[network]" > /etc/wsl.conf'
sudo bash -c 'echo "generateResolvConf = false" >> /etc/wsl.conf'
sudo chattr +i /etc/resolv.conf

接下来下载东西就都没有问题了。

补充：今天又碰到这个问题了，这次是ssh的时候无法解析hostname，
又get到了一种新的解决办法：
直接在/etc/resolv.conf中加入dns服务器地址

| nameserver 202.96.134.133
nameserver 8.8.8.8

然后重新启动wsl就可以了
