ubuntu apt-get下载报failed to fetch错误,请问如何解决

Question

Ubuntu apt-get 下载源错误,尝试过清除 /var/lib/apt/lists/*
可还是无法使用apt-get,是需要换dns吗?

Answer 1

已经解决了,现在补上答案
原因是ubuntu自带的源不给力,所以我换成国内的源了

首先备份源列表

sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

换源方法

sudo vim /etc/apt/sources.list

将这里的源替换成国内的源,我用的是清华大学的镜像源,当然网易和阿里的源都挺不错的

默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse

# 预发布软件源，不建议启用
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse

然后 sudo apt-get update

最后附上国内几个镜像源网址
