提示：如果上述站点 Linux Deepin 镜像无法使用，可发送邮件到 [email protected]，我们会及时沟通处理。
在使用上述更新源时，我们需要更改的是“Linux Deepin 特有源”部分。如果将更新源列里面的站点全部更换，请确保要使用的站点提供了 Ubuntu 镜像。
示例：使用系统实验室提供的 Linux Deepin 镜像，则 /etc/apt/sources.list 文件变为（更改需要管理员权限）：
deb http://packages.linuxdeepin.com/ubuntu precise main restricted universe multiverse
deb http://packages.linuxdeepin.com/ubuntu precise-security main restricted universe multiverse
deb http://packages.linuxdeepin.com/ubuntu precise-updates main restricted universe multiverse
#deb http://packages.linuxdeepin.com/ubuntu precise-proposed main restricted universe multiverse
#deb http://packages.linuxdeepin.com/ubuntu precise-backports main restricted universe multiverse

deb-src http://packages.linuxdeepin.com/ubuntu precise main restricted universe multiverse
deb-src http://packages.linuxdeepin.com/ubuntu precise-security main restricted universe multiverse
deb-src http://packages.linuxdeepin.com/ubuntu precise-updates main restricted universe multiverse
#deb-src http://packages.linuxdeepin.com/ubuntu precise-proposed main restricted universe multiverse
#deb-src http://packages.linuxdeepin.com/ubuntu precise-backports main restricted universe multiverse

deb http://pkg1.skyshe.com:8737/deepin precise main non-free

然后，刷新列表：
sudo apt-get update #必须对列表刷新
