Ubuntu E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? 错误

一、异常错误

• apt install 时遇到这个问题，无法获取某些存档

二、原因

• 网络连接超时

二、解决方法

1.网络问题

• 网关错误拦截了数据包或者防火墙故意将其屏蔽在外
• 可以尝试更换网络或者代理，再次下载
• 或者更改配置文件sudo vim /etc/resolv.conf
• 添加nameserver 8.8.8.8

2.source的问题

可以尝试运行

• apt-get update
• 或apt-get update　--fix-missing

依然报错，则更换source源

• 修改Ubuntu默认apt下载源
• sudo vim /etc/apt/sources.list

将文件内容替换成

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

参考： Ubuntu 16.04 source.list 国内更新源

最后要更新一下，这个命令就相当于更新软件商店里面的目录

• sudo apt-get update

再升级，相当于与软件目录对比，更新本地已经下载的软件

• sudo apt-get upgrade
