Fix Ubuntu Missing Yum Command

In Ubuntu systems, the ‘yum’ command is not used, instead package management is done with the ‘apt’ command. To address this issue, you can follow these steps:

1. Install software package using apt command: sudo apt install .
   For example, to install the curl package, you can run sudo apt install curl.
2. Update the list of software packages: sudo apt update
   This will update the list of available software packages so that you can access the latest information on packages.
3. Upgrade the installed software packages: sudo apt upgrade
   This will upgrade the installed software packages to the latest version.
4. If you really want to use the yum command, you can try installing the yum tool, but this is not recommended as Ubuntu system does not natively support yum.

Please note that although yum and apt are both package management tools, they use different software package formats, so the yum command cannot be directly used in Ubuntu system.
