本文主要是介绍linux deploy换国内源，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
我的Linux deploy版本是Ubuntu 18.0.4，架构选的是armhf，感觉官方源速度太慢，于是打算换国内源，网上搜了Ubuntu 18.0.4的换源教程，但执行
sudo apt update时会报错，
无法下载 https://mirrors.ustc.edu.cn/ubuntu/dists/bionic/main/binary-armhf/Packages 404 Not Found网上查了一下发现一篇文章 Ubuntu支持armhf 的国内源
原来是我的源选错了，重新选用下面的源
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-backports main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-proposed main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-security main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-updates main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-backports main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-proposed main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-security main multiverse restricted universe
deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-updates main multiverse restricted universe然后执行
sudo apt update
sudo apt upgrade终于成了。
这篇关于linux deploy换国内源的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
