When I first started building web servers using Linux I would run into the following message that would display whenever I SSH’ed into the server, and didn’t understand why I needed to restart the computer:

Here’s an example of what you might see in that file:
Typically, these updates are security patches and need to be updated immediately to prevent any potential issues. So, I would recommend rebooting your machine, either using your hosting company or directly via running the following command:
The server should reboot and you should no longer see that message.
