apt-get 更新的问题

我有一个 digitalocean 云服务器 ( Ubuntu 16.04)，我已ufw在上面设置了。当我尝试运行 时apt-get update，我得到以下信息：

Err:1 http://mirrors.digitalocean.com/ubuntu xenial InRelease

我尝试过的：

mv /var/lib/apt/lists /var/lib/apt/lists.old 
apt-get clean
apt-get update

我的 resolv.conf 和我的名称服务器的输出：

cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

cat /etc/network/interfaces.d/50-cloud-init.cfg
# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
auto lo
iface lo inet loopback
    dns-nameservers 67.207.67.2 67.207.67.3

ufw已配置为apt-get通过允许端口 53 和端口 123 来允许。即使禁用也会ufw产生相同的结果，我一直在谷歌搜索这个问题，它似乎很常见，但没有一个修复方法对我有用，有人知道这个问题的任何修复方法吗？

答案1

您能否尝试以 root 用户身份使用以下命令进行进一步调试？

我的假设是您可能不会覆盖 DO 的 DNS，因为它们用于解析 mirrors.digitalocean.com 和其他需要的东西（监控、ntp......）。

您可能希望添加自己的名称服务器（67.207.67.2 67.207.67.3），其优先级低于 DO 的名称服务器，而不是替换它们。

我现在没有准备好水滴来检查，但这显然是一个提示
