Upgrading a system can be a daunting task, especially if it is an off-line system. An off-line system is one that is not connected to the internet and cannot access online resources. The good news is that you can still upgrade your system even when it is not connected to the internet. This article will explain how to upgrade your system off-line using ISO and Yum.

Introduction

An ISO file is an image file that contains all the data required to install a new operating system. A Yum is a package manager that helps you install, update and manage packages on your system. By combining ISO and Yum, you can upgrade your system off-line, even when it is not connected to the internet.

The Advantages of Upgrading Off-Line

There are several advantages to upgrading your system off-line. Firstly, it ensures that your system is always up-to-date and secure. Secondly, it eliminates the risk of downloading malware from the internet. Thirdly, it reduces the chances of encountering compatibility issues that may arise when upgrading your system online. Finally, it ensures that your system will always be operational even if there is an internet outage.

Steps to Upgrade Your System Off-Line

Step 1: Download the ISO File

The first step to upgrading your system off-line is to download the ISO file. You can download the ISO file from the official website of your operating system. For example, if you are using Fedora, you can download the ISO file from the Fedora website.

Step 2: Burn the ISO File to a CD or USB

Once you have downloaded the ISO file, you need to burn it to a CD or USB drive. This will allow you to install the new operating system from the CD or USB drive.

Step 3: Boot from the CD or USB

The next step is to boot your system from the CD or USB drive. To do this, you need to change the boot order in your system’s BIOS. You can access the BIOS by pressing the Del, Esc or F2 key during the boot process. Once you are in the BIOS, you can change the boot order to make the CD or USB drive the first boot device.

Step 4: Install the New Operating System

Once your system has booted from the CD or USB drive, you can start the installation process. The installation process will vary depending on the operating system you are installing. In general, you will need to select the language, time zone and keyboard layout. You will also need to partition your hard drive and select the installation location.

Step 5: Configure Yum

After the installation process is complete, you need to configure Yum. Yum is a package manager that helps you install, update and manage packages on your system. To configure Yum, you need to create a Yum repository. A Yum repository is a collection of packages that Yum uses to install and update packages on your system.

To create a Yum repository, you need to download the RPM packages from the official website of your operating system. You can then create a directory on your hard drive and place the RPM packages in that directory. Once you have created the directory, you need to create a Yum repository configuration file. The Yum repository configuration file tells Yum where the packages are located and how to access them.

Step 6: Update Your System

Once you have configured Yum, you can use it to update your system. To update your system, you need to run the following command:

yum update

This command will update all the packages on your system to the latest version. Yum will download the required packages from the Yum repository and install them on your system. If there are any dependencies between packages, Yum will automatically resolve them and install the packages in the correct order.

Step 7: Install New Packages

In addition to updating your system, you can also use Yum to install new packages. To install a new package, you need to run the following command:

yum install [package-name]

Replace [package-name] with the name of the package you want to install. For example, if you want to install the nano text editor, you would run the following command:

yum install nano

Yum will download the package from the Yum repository and install it on your system. If there are any dependencies between packages, Yum will automatically resolve them and install the packages in the correct order.

Conclusion

Upgrading your system off-line can be a complex process, but by following the steps outlined in this article, you can upgrade your system with ease. By using ISO and Yum, you can ensure that your system is always up-to-date and secure, even when it is not connected to the internet. With a little bit of preparation, you can easily upgrade your system off-line and enjoy the benefits of a new and improved operating system.
