Can't find yum and installation method in Ubuntu system!

yum is the package manager in the Red Hat series distributions (such as RHEL and CentOS), while Ubuntu uses another package manager called apt (Advanced Package Tool ).

In Ubuntu system, you can use apt command to manage software packages. Following are the basic steps to install packages in Ubuntu system:

1. Update package index
   
   Before performing any installation operations, first execute the following command to update the package index:

   sudo apt update

2. Install packages
   
   Use the following command to install a specific package:

   sudo apt install package_name

   Replace "package_name" with the name of the package you want to install.

   For example, to install the Apache HTTP server, you can execute the following command:

   sudo apt install apache2

   If you want to install multiple packages, just concatenate their names separated by spaces:

   sudo apt install package1 package2 package3

3. Confirm installation
   
   After executing the installation command, the system will prompt you to confirm the installation. Press the "Y" key and press Enter to confirm the installation.
4. finish installation
   
   The installation process will run automatically and display the installed software packages and their version information when completed.

Please remember that using apt for package management is a recommended practice in Ubuntu systems. If you need to install a specific package in your Ubuntu system, use apt command instead of yum.
