Learn To Install a Package on Ubuntu without Internet – Offline APT Package Manager

Before you learn to use apt-offline to install your packages, you must install apt-offline on your Ubuntu server without an internet connection. If you don’t have it, proceed to the following steps to complete this guide.

Step 1 – Install apt-offline on Offline Ubuntu System

If you don’t have apt-offline installed on your server, you can download the package from a system with internet access and transfer it to your offline system. To get the package, you can visit the official website and get your desired package that is suited for your Ubuntu system.

Download apt offline packages from Ubuntu

Step 2 – Set a Signature File on the Ubuntu System without Internet

From your offline Ubuntu system, you need to generate a signature file for apt-offline. This file includes information about all the updates and packages needed by the system. To do this, you can use the following command:

sudo apt-offline set /path/to/signature-file.sig

Remember to replace the /path/to/signature-file.sig with your desired path and file name.

Step 3 – Download a Package on an Online System

At this point, you need to transfer the signature file you have created in the offline Ubuntu system to the system that has internet access.

Then, you can use the apt-offline command on your online system to download the required packages:

sudo apt-offline get -d /path/to/downloaded-packages /path/to/signature-file.sig

This command downloads the necessary packages and updates to the signature file.

Once your download is completed, you must transfer the packages to your Ubuntu system without an internet connection.

Step 4 – Install Packages with apt-offline on Ubuntu without Internet

At this point, you can easily install the transferring packages on your offline system with the following command:

sudo apt-offline install /path/to/downloaded-packages

Finally, run the system update to apply the changes:

sudo apt update

Note: The apt update command does not require an internet connection; it simply updates the system’s packages.

When you want to use an offline apt package manager, you need to consider the following notes:

  • Be sure that the version of apt-offline is the same on both the offline and online systems.
