前提是已取得root权限

首先将/etc/apt/sources.list备份一下，然后修改它

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

sudo dedit /etc/apt/sources.list

显示如下

## Generated by deepin-installer
deb [by-hash=force] http://repo.xc.cbirc/desktop-professional eagle main contrib non-free
#deb-src [by-hash=force] http://repo.xc.cbirc/desktop-professional eagle main contrib non-free

改为

deb [by-hash=force] https://professional-packages.chinauos.com/desktop-professional eagle main contrib non-free

清除软件仓库缓存

sudo apt-get clean

更新软件仓库

sudo apt-get update

接下来安装光盘工具brasero或k3b测试下

sudo apt-get install brasero

安装的deb包都在/var/cache/apt/archives下面
