  2. I have the Ubuntu 19.04 DT installed. I wanted to upgrade to 20.04 but when I ran the Installer it tells me that it will take many hours. After waiting overnight nothing happened. This went on for three attempts. I do have a fast internet connection

    I am frustrated and I have downloaded the ISO version of 20.04. Can I go ahead and install the 20.04 directly from this? I know that I have to put it on a flash drive first.

  3. When I try to install MATE on Ubuntu Server 20.04 I get GNOME 3. This happens with the packets mate-desktop, mate-desktop-environment and ubuntu-mate-desktop.

    • @Muhammad,
      Yes its possible, as you can install any desktop environments like cinnamon, mate, gnome or xfce with one single command.

      Install Gnome Desktop:

      $ sudo apt-get install gnome-shell ubuntu-gnome-desktop
      

      Install Mate Desktop:

      $ sudo apt-get install ubuntu-mate-desktop
      

      Install Cinnamon Desktop:

      $ sudo apt-get install cinnamon-desktop-environment
