 - Alpine Linux Edge: `apk add vala-language-server`
 
-- Ubuntu 18.04, 20.04 and elementaryOS
-
-  In order to install VLS, you need Vala 0.48 or later, which is only available
-  by default on Ubuntu 20.04. You can get an up-to-date version of Vala
-  from the Vala Team's Vala-Next repository. First you need to remove older
-  Vala components:
-
-    ```sh
-    sudo apt-add-repository ppa:vala-team/next
-    # If you have 0.40 and 0.48, there may be random issues popping out
-    sudo apt-get remove valac-0.40-vapi "libvala.*-0.40-0"
-    sudo apt-get install valac-0.48 valac-bin
-    ```
-
-  Now you can install the Vala Language Server:
-
-    ```sh
-    sudo add-apt-repository ppa:prince781/vala-language-server
-    sudo apt-get update
-    sudo apt-get install vala-language-server
-    ```
-- Fedora 32:
-
-    ```sh
-    sudo dnf copr enable prince781/vala-language-server
-    sudo dnf -y install vala-language-server
-    ```
