1.首先修改ubuntu14.04的更新源，使用sudo gedit /etc/apt/sources.list命令编辑更新源列表文件，在修改之前需要备份一下该文件。
deepinlinux更新源如下：
deb http://packages.linuxdeepin.com/ubuntu trusty main restricted universe multiverse
deb http://packages.linuxdeepin.com/ubuntu trusty-security main restricted universe multiverse
deb http://packages.linuxdeepin.com/ubuntu trusty-updates main restricted universe multiverse
deb http://packages.linuxdeepin.com/ubuntu trusty-proposed main restricted universe multiverse
deb http://packages.linuxdeepin.com/ubuntu trusty-backports main restricted universe multiverse
deb-src http://packages.linuxdeepin.com/ubuntu trusty main restricted universe multiverse
deb-src http://packages.linuxdeepin.com/ubuntu trusty-security main restricted universe multiverse
deb-src http://packages.linuxdeepin.com/ubuntu trusty-updates main restricted universe multiverse
deb-src http://packages.linuxdeepin.com/ubuntu trusty-proposed main restricted universe multiverse
deb-src http://packages.linuxdeepin.com/ubuntu trusty-backports main restricted universe multiverse
deb http://packages.linuxdeepin.com/deepin trusty main universe non-free
deb-src http://packages.linuxdeepin.com/deepin trusty main universe non-free
deb http://packages.linuxdeepin.com/deepin trusty-updates main universe non-free
deb-src http://packages.linuxdeepin.com/deepin trusty-updates main universe non-free
当然也可以使用ppa，执行
sudo apt-add-repository ppa:noobslab/deepin-sc
sudo apt-get update
2.如果出现秘钥错误的提示，需要下载秘钥并且导入，执行
wget http://packages.linuxdeepin.com/deepin/project/deepin-keyring.gpg
gpg --import deepin-keyring.gpg
gpg --list-keys #列出秘钥
将密钥导出到 apt-key
sudo gpg --export --armor 209088E7 | sudo apt-key add -
sudo apt-get update
3.安装所需软件，执行
sudo apt-get install deepin-music-player #[安装深度音乐]
sudo apt-get install deepin-media-player #[安装深度影音]
sudo apt-get install deepin-terminal #[安装深度终端]
sudo apt-get install deepin-screenshot #[安装深度截屏]
在这期间如果出现依赖关系的错误提示，执行
sudo apt-get install -f
4.对于以上安装的补充
深度音乐安装后可以播放本地音乐，网上有人开发了一款百度音乐的插件，可以播放百度音乐盒中收藏的音乐
安装此插件需先安装编译时的相关依赖包(cython libwebkitgtk-dev Python-dev git)
sudo apt-get install cython libwebkitgtk-dev git
还需要安装pyjavascriptcore
git clone https://github.com/sumary/pyjavascriptcore.git
cd pyjavascriptcore
sudo python setup.py install
现在可以安装百度音乐插件了
git clone https://github.com/sumary/dmusic-plugin-baidumusic.git
cd dmusic-plugin-baidumusic
注意：在下面拷贝插件到深度音乐插件目录之前，需要先打开深度音乐，让它自动创建插件文件夹
cp -r baidumusic ~/.local/share/deepin-music-player/plugins/
深度截屏安装完成后在ubuntu上快捷键是不好使的，而且需要在dash里找到它或者是在终端中输入命令，这样用起来很不方便，可以使用ubuntu的自定义快捷键，在设置中找到键盘-》快捷键，添加一个新的，命令输入deepin-screenshot 即可，快捷键可以使用ctrl+alt+a。
