debian 执行apt-get update 无法更新的问题

美擦

一、运行了一个debian容器，进入容器后执行apt-get update报错

root@nginx-demo-deployment-59fbc48594-4z8h9:/# apt-get update
Err:1 http://deb.debian.org/debian buster InRelease
  Temporary failure resolving 'deb.debian.org'
Err:2 http://security.debian.org/debian-security buster/updates InRelease
  Temporary failure resolving 'security.debian.org'
Err:3 http://deb.debian.org/debian buster-updates InRelease
  Temporary failure resolving 'deb.debian.org'

二、修改源

查看当前设置源

oot@nginx-demo-deployment-59fbc48594-4z8h9:/# cat /etc/apt/sources.list
# deb http://snapshot.debian.org/archive/debian/20201209T232235Z buster main
deb http://deb.debian.org/debian buster main
