Ubuntu Focal Server with Desktop

I used a Focal Server Image and then installed:

apt-get install --yes --no-install-recommends ubuntu-unity-desktop ttf-ubuntu-font-family gnome-shell-extensions

but the desktop still looks different to the original desktop from the desktop version. I then tried several packages like gnome-shell-extension-desktop-icons but without success.

Does someone know what exactly needs to be done to get the same icons and possibly settings?

Left Server Version, Right Desktop Installer Version:

Solution 1:

Looks like you're missing the Yaru theme. You may be able to get the look somewhat close to the stock desktop with:

sudo apt install yaru-theme-unity yaru-theme-gtk yaru-theme-icon yaru-theme-sound

There are a number of Yaru theme packages available, and you can find them in apt like this:

sudo apt search yaru

This will give you something like:

yaru-theme-gnome-shell/focal-updates,focal-updates,now 20.04.11.1 all [installed,automatic]
  Yaru GNOME Shell desktop theme from the Ubuntu Community

yaru-theme-gtk/focal-updates,focal-updates,now 20.04.11.1 all [installed,automatic]
  Yaru GTK theme from the Ubuntu Community

yaru-theme-icon/focal-updates,focal-updates,now 20.04.11.1 all [installed,automatic]
  Yaru icon theme from the Ubuntu Community

yaru-theme-sound/focal-updates,focal-updates,now 20.04.11.1 all [installed,automatic]
  Yaru sound theme from the Ubuntu Community

yaru-theme-unity/focal-updates,focal-updates 20.04.11.1 all
  Yaru Unity theme from the Ubuntu Community

_{Note: The above output comes from a 20.04 LTS Desktop installation. As you've installed the Unity theme, the first apt command in this answer replaces yaru-theme-gnome-shell with yaru-theme-unity.}
