How to fix the Ubuntu Kernel Panic issue

What is kernel Panic issue on Linux machine?

In basic terms a kernel panic on Linux machine is a situation when kernel can’t load properly and fails to boot properly or crashes. When the Linux kernel detects an error from which it cannot recover itself. This happens rarely but it is majorly caused due to hosed updates or failing hardware or missing drive update or partitions (like /etc/fstab file entry wipeout) results in panic or voluntary halt to system activity.

Why does kernel Panic issue occurs?

A kernel panic may occur as a result of hardware failure or a software bug in the Linux Based Operating System. Primarily, two things happen when Linux kernel is unable to proceed : the Software runs out of resources and hardware does something unexpectedly or does not do anything. This might happen due to hosed updates, failing hardware, failed or missing drive update or partitions. It also occurs in order to prevent your Linux server from data corruption, risking security breaches as system is in unstable state. So Operating System stops to prevent damage and facilitates diagnosis of the error and, in usual cases, restart.

What is the effect it has on Linux Server?

It might end up crashing your Linux Server or failure to boot.
