How to install cPanel and Softaculous on Ubuntu 20.04 server

Linux Ubuntu

Installing Softaculous on your Ubuntu 20.04 server

In order to install softaculous on your server you need to install cpanel.

Minimum requirements for cpanel:

  • Processor - 1.2 GHz
  • RAM - 2GB
  • Disk space - 25 gb

Recommended requirements for cpanel:

  • Processor - 2.1 GHz
  • RAM - 4 gb
  • Free disk space - 45 gb

Creating a server under Softaculous thanks to Serverspace.

Let's create a server that will meet the recommended characteristics.

To create servers, do the following steps:

  • Login to your personal area, go to the vStack cloud > Servers tab and click Create Server:


  • Select the recommended requirements and click Create:



  • If you need to install any applications, you can do this during the deployment phase:


  • Don't forget to configure access to the server. (Either via a private ssh key or using login + password)


Automatic installation

You can do the installation via an automated command or you can do it manually. (It's possible that the installation fails, so if you can't install cpanel automatically, install it manually.)

This is usually because a certain software package was already installed.

cd /home && curl -o latest -L && sh latest


You will probably get a "curl not found" error. This means you don't have the "curl" utility installed.
Update packages with the command:

apt-get update && apt-get upgrade


After upgrading packages, install the "curl" utility.

apt-get install curl -y

You need to install "perl" so that cpanel can start the installation.

Then try to install "cpanel" again automatically:

apt-get install perl

If it succeeds you will see this window:


Manual installation

If the automatic installation doesn't work, follow the instructions below:
