问题描述:

  多次在apt install时候遇到E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? 的error。

  Error报的信息显示是这个包向source里的资源下载失败了,但是原因是多种多样的,这里做了个总结,以防下次踩坑:

问题解决:

  1- source本身的问题

  根据提示,我们首先应当 apt-get update 一下source,如果在apt-get update后依然报这个error,那就说明这个source本省就有错误,尝试apt-get update --fix-missing后依旧报这个error,果断换source。

  输入命令:

sudo cp sources.list sources.list.bak

  就是先将sources.list备份到sources.list.bak

  **将 /etc/apt/sources.list 的内容换成:

**

  最后sudo apt-get update一下就OK了。

  2- 网络的问题

  网关错误拦截了数据包或者防火墙故意将其屏蔽在外(比方update 包含有google-chrome浏览器的source时候,ip 会自动重定向至6.6.6.6) 

  sudo vim /etc/resolv.conf

  添加:

nameserver 8.8.8.8
nameserver 223.5.5.5
nameserver 223.6.6.6

  或是换网络试一下或者参见该配置代理即可。

  最后sudo apt-get update一下就OK了。


愿你出走半生,归来仍是少年
