I recently installed Ubuntu 18.04 and I'm not keen on the desktop environment. I want the desktop env. I used to have in Ubuntu 14.04. How can I get it?

I've attempted to use this answer, but when I try to install the Unity's 7.2.5 version using the command:

apt install unity=7.2.5

it gives me 

E: Version '7.2.5' for 'unity' was not found

For sure I need to add a PPA for this, but which one!?

To install Unity you need to follow these steps:

  • Open a terminal (Ctrl+Alt+T) and use the following command:

    sudo apt install ubuntu-unity-desktop

  • At the installation time, you’ll be asked whether you want to switch to LightDM.

    Configuring lightdm

    A Display manager is what you see on the login screen.

    • If you want Unity like login screen: select lightdm
    • If you want to keep the default login screen in Ubuntu 18.04: select gdm3

    Just select the one you want and press enter to move ahead with the installation procedure.

    Choosing default display manager

  • Once the installation is complete, restart your system. At the login screen, click on the Ubuntu symbol in LightDM or gear symbol in GDM.

    Login Screen

  • In here, you can see the option to use Unity desktop environment.

    Choose Desktop environment

I think Tasksel is best and simplest way. Type: 

sudo apt-get install tasksel

And then:

sudo tasksel

Uncheck GNOME desktop and check Ubuntu desktop. Then click OK. Reboot and you're done.

It's better to install Ubuntu from mini.iso - Ubuntu Netboot images. When you're asked to choose any environment, don't check any and continue installation. Once the installation's completed, login into clear OS and install Unity by:

sudo apt install ubuntu-unity-desktop

That's it! You'll get absolutely clear Ubuntu 18.04/18.10 with only Unity/LightDM
