If you too want to install it then open your terminal and type as
sudo -H gedit /etc/apt/sources.list
Then add deb lines like these at the end of the opened file, possibly replacing
trusty with the codename of another Ubuntu release (but don't make any other changes):
deb http://packages.linuxdeepin.com/deepin trusty main non-free universe
deb-src http://packages.linuxdeepin.com/deepin trusty main non-free universe
Currently the repository has versions for trusty (Ubuntu 14.04 LTS) and precise (Ubuntu 12.04 LTS). You can browse the repository to see what releases are supported, when you install. To find the codename for your Ubuntu release, see the Releases wiki page or run
lsb_release -c. If no version is available specifically for your release, you can try the version built for another release (pick one close to yours if possible).
After adding the appropriate lines, save the file, quit the text editor, and return to the terminal.
Paste these lines one by one:
gpg --import deepin-keyring.gpg
sudo gpg --export --armor 209088E7 | sudo apt-key add -
Then we are almost done. in the terminal paste these lines one by one
sudo apt-get update
sudo apt-get install dde-meta-core
Thats it, That will install deepin DE in your computer and from login screen you can choose the DE.
