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

Err:1 http://security.ubuntu.com/ubuntu bionic-security InRelease
  Temporary failure resolving 'security.ubuntu.com'
Err:2 http://archive.ubuntu.com/ubuntu bionic InRelease

W: Some index files failed to download. They have been ignored, or old ones used instead.

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。
