No Linux No Life – How to Fix “REMOTE HOST IDENTIFICATION” Error

Can you imagine a life without Linux?

C’mon, Linux is something you can’t live without regardless of your knowledge of the OS’s existence. Google, Apple, Amazon, Meta, SAP, Oracle,,, and name a few, not only major tech companies in the world but also almost small businesses in most of the world are heavily depending on Linux in their data-storing backend systems. Without a basic knowledge of Linux, you can’t survive in the tech world.

While using Linux, CUI is the interface I grew familiar with, and I do believe CUI is the universally acceptable skill we all can take advantage of in the tech field wherever we go, while GUI changes in every version, which doesn’t count as a skill in my universe.

Anyways, in this new Linux series, No Linux, No Life, I will cover my knowledge and spontaneous errors I encounter during my interaction with the OS. And I’ll use this series as my own notes for my future self. Ever since I started using Ubuntu Server 20.04 as my main home hub for file storing systems, my interaction with the open-source OS has changed 180.

Here, I’ll cover how I fixed the “REMOTE HOST IDENTIFICATION” error.

On my Linux laptop, System 76’s Galago Pro (2018 model), I encounter an error while trying to access one of the virtual machines on the laptop, more specifically the CentOS server.

To fix the issue, type the following command:

ssh-keygen -R 192.168.0.107

Then, I had no trouble accessing the server. Phew…
