How to install the Linux operating system?

There are typically multiple methods to install software on a Linux system, with two common ones being:

1. Installing with a package manager
   Most Linux distributions come with a package manager that allows you to easily download, install, and update software packages. Common package managers include:
2. In Debian/Ubuntu, use the apt-get command, such as sudo apt-get install software-name.
3. For Fedora/RHEL/CentOS systems, you can install software by using the yum command, such as sudo yum install software-name.
4. On Arch Linux/Manjaro, you can install software by using the pacman command, such as sudo pacman -S software-name.
5. Compile and install from source code
   If the required software package is not provided by the package manager, or if you want to use the latest version of the software, you can compile and install from the source code. The typical steps are as follows:
6. Download the source code package, usually a .tar.gz or .tar.bz2 file.
   Extract the source code package using the command tar -xzvf source-code.tar.gz or tar -xjvf source-code.tar.bz2.
   Navigate to the extracted directory, typically cd source-code.
   Read the README or INSTALL file of the software package to understand necessary dependencies and installation steps.
   Typical installation steps include running the ./configure command to configure the software, then running the make command to compile the software, and finally running the sudo make install command to install the software.

Before using any installation method, it is recommended to update the system first to ensure you have the latest software packages and security patches. You can update the system using the following command:

1. Update and upgrade your Debian/Ubuntu system by running “sudo apt-get update && sudo apt-get upgrade”.
2. Update Fedora/RHEL/CentOS using the command: sudo yum update.
3. Update the system using pacman on Arch Linux or Manjaro: sudo pacman -Syu.
