    You can do this by pressing Ctrl+Alt+T on your keyboard. Alternatively, you can press the super user (Windows) key on your keyboard to open the Activities menu and search for "terminal".

    If you prefer, you can check for any available package updates with the "check-update" subcommand. If you already know what packages you need to update or you just want to update them all, you can skip this step.
    • In the terminal, write yum check-update and press Enter .
    • All of the packages that yum can update will be listed.

    To do this, type yum update . Without any package names with it, the yum update command will try to update every package you have. [1]
    • To specify a package (like the ones found in Step 3 with "check-update"), type its name after the yum update command.
    • Once the packages are done updating, you can close out of the terminal.

      Tips

      • In RHEL 8 and RHEL 9, software management is based on dnf . [2] However, yum commands have been maintained (as a dnf symlink in RHEL 8 and a dnf alias in RHEL 9) to ensure compatibility with RHEL 7.

      • If you are restricted from using the yum command, put the sudo command before it (i.e. sudo yum update ). Just note that when you use sudo , you'll have to verify the super user (admin) password for verification.

      • You can also use yum upgrade instead of yum update . The yum upgrade command will update your packages and delete obsolete ones. As such, yum update is the safer update option, so you don't lose the packages you're currently using.
