- When starting up CentOS, a service is automatically run in the background that checks to see if there are any available updates. Be patient as it may take a few minutes to run. If there are available updates for your system, an open box will appear in the upper right corner near the clock and a message box will open up with the Updates Available title.
Click the View Updates… button.
- The Package Updater will open.
Click Apply updates.
CentOS will now resolve all dependencies and then download and install all updates. You may be prompted to accept some downloads.
- If an update requires a reboot, you will be prompted to do so.
Click Reboot now.
CentOS is now ready to use.
