Linux Debian10更新源

新安裝的Debian系統，經常出現安裝不了軟體的情況，因為預設的源是國外，是以導緻無法安裝，我們可以通過修改源的方式進行處理。

1.編輯 /etc/apt/sources.list 檔案以修改更新源

vim /etc/apt/sources.list

2.寫入如下内容

deb http://mirrors.163.com/debian/  stretch main non-free contrib

deb http://mirrors.163.com/debian/  stretch-updates main non-free contrib

deb http://mirrors.163.com/debian/  stretch-backports main non-free contrib

deb-src http://mirrors.163.com/debian/  stretch main non-free contrib

deb-src http://mirrors.163.com/debian/  stretch-updates main non-free contrib

deb-src http://mirrors.163.com/debian/  stretch-backports main non-free contrib

deb http://mirrors.163.com/debian-security/  stretch/updates main non-free contrib
