Ajenti is written in Python, requires very few resources, and compatible with many Linux distributions. So It is the best choice for you if you want to monitor and manage your server from a web-based interface.

In this tutorial, we will explain how to install Ajenti Control Panel on Ubuntu 18.04.

Requirements

• A server running Ubuntu 18.04.
• A root password is set up on your server.

Getting Started

Before starting, you will need to update your system with the latest version. You can do this by running the following command:

apt-get update -y
apt-get upgrade -y

Once your server is updated, restart your server to apply the changes.

Install Required Dependency

Before starting, you will need to install python-imaging dependency on your server. First, download the python-imaging package with the following command:

wget http://mirrors.mit.edu/ubuntu-ports/pool/universe/p/pillow/python-imaging_3.1.2-0ubuntu1.1_all.deb

Once downloaded, install the downloaded package with the following command:

dpkg -i python-imaging_3.1.2-0ubuntu1.1_all.deb

You should see the following error:

Selecting previously unselected package python-imaging.
(Reading database ... 28634 files and directories currently installed.)
Preparing to unpack python-imaging_3.1.2-0ubuntu1.1_all.deb ...
Unpacking python-imaging (3.1.2-0ubuntu1.1) ...
dpkg: dependency problems prevent configuration of python-imaging:
 python-imaging depends on python:any (<< 2.8).
 python-imaging depends on python:any (>= 2.7.5-5~).
 python-imaging depends on python-pil; however:
  Package python-pil is not installed.

dpkg: error processing package python-imaging (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 python-imaging

You can fix the above error by installing python-imaging dependency as shown below:

apt --fix-broken install

Once all the required dependencies are installed, you can proceed to the next step.

Install Ajenti

By default, Ajenti is not available in the Ubuntu 18.04 default repository. So you will need to add Ajenti repository to your system.

First, download and import Ajenti repository GPG key with the following command:

wget http://repo.ajenti.org/debian/key -O- | apt-key add -

Next, add Ajenti repository with the following command:

echo "deb http://repo.ajenti.org/ng/debian main main ubuntu" | tee /etc/apt/sources.list.d/ajenti.list

Next, update the repository and install Ajenti with the following command:

apt-get update -y
apt-get install ajenti -y

Once the installation has been completed, you should get the following output:
