In this tutorial, we learn the steps to install popular Deepin Dekstop- DEE on POP_OS 20.04 LTS or 21.04 Linux using the command terminal.
Deepin is one of the most beautiful Linux distro based on the Debian operating system. However, there are many people who refrain themselves from using either because of its origin or slow repository. Hence, one of the best ways to experience its beauty is by installing the Deepin Desktop GUI on our existing POP_OS operating systems.
Moreover, installing a new operating system is also cumbersome if you have already have set up applications you required on it. In such as scenario, installing an extra GUI apart from the default one will be a good idea.
POP_OS comes with a popular Gnome desktop environment, however being a Linux distro, users are free to install any popular Linux GUI with few commands such as Cinnamon, XFCE, etc. However, unlike other GUI, the Deepin Linux desktop is not available through the default base repository of POPOS. Therefore, to get it we have to add a repo manually. And the best way is to use the package repo made available by UbuntuDDE, an Linux operating system based on Ubuntu and running with DDE.
How to install Deepin Desktop Environment (DDE) on POP!_OS
The command given here can also be used for other Ubuntu systems such as Ubuntu 20.04/18.04; Linux Mint, Elementary OS, MX Linux, and more…
• You should have existing POP!_OS
• A non-root user with sudo access
• Internet connection
• 4GB RAM for good performance
2. Run update and install software properties package
To make sure all the packages are up to date on your system and to add PPA also install Software Properties to get packages from independent software vendor software sources.
sudo apt update && sudo apt upgrade -y
sudo apt install software-properties-common -y
2. Add Ubuntu DDE PPA
Well, as I said this desktop environment is not available to install via the official repository, hence we have to add the third-party PPA. Well, if you are using POP OS for some production work, then we don’t recommend going for the PPA. However, for standard user PC, you can add the given PPA using the command.
sudo add-apt-repository ppa:ubuntudde-dev/stable
Press the Enter key when it asks for and after that run again the system update:
sudo apt update
3. Command to install Deepin Desktop on POP_OS
Once you have added the repository, the next thing is to run the APT package manager command for the installation of Deepin Desktop GUI on POP 20.04 or other versions you are using.
For a standard installation, run:
sudo apt install ubuntudde-dde
Whereas for full, use:
sudo apt install ubuntudde-dde ubuntudde-dde-extras
When it asks to set Display manager, select GDM3 for default POP OS login interface or LightDM for Deepin Login interface.
4. Reboot your system
Once the installation is completed, reboot your system to apply the changes. You can restart either using the GUI interface of your computer or simply enter the following command
5. Login Pop!_OS with Deepin Desktop
Now we have two desktops, one is the default Gnome and the other Deepin, hence we have to select which we want to use from the login interface. Click on the User and then the Gear icon, given on the right bottom side.
If you have selected LightDM then you will get something given in the screenshot as login interface; then click on the Deepin globe icon to select the GUI interface.
Note: Those who want to reconfigure the Display manager in the future can use:
sudo dpkg-reconfigure gdm3

Select gdm3 instead lightdm
