 | 1 kmahyyg Jul 8, 2017 via Android 换 apt 源 |
 | 2 expy Jul 8, 2017 /etc/apt/sources.list 里填个国内的源，比如阿里云。版本号应该是 16.04.1 吧。 |
 | 3 7654 Jul 8, 2017 看到题目，下意识的登录各机器看了看，16.04.2 又更新了。。 换源即可 |

 | 16 chromee Jul 8, 2017 via Android 你本地域名解析有问题 检查一下是 dns 还是什么软件造成的 |
 | 17 XiaoxiaoPu Jul 8, 2017 @merrillyeung 端口都不是正常端口，那应该不是 DNS 劫持，检查下你的代理设置吧 |
 | 18 zsj950618 Jul 8, 2017 是你的 apt 被配置了代理，去 /etc/apt/ 下看下配置，把代理删掉就好了 |
| 19 merrillyeung OP @XiaoxiaoPu 代理处一致显示 NONE，居然要按一下 apply system wide 才行 谢啦 |
 | 20 qiyuey Jul 8, 2017 这个是代理吧 |
