How To Install crash on Ubuntu 20.04
Introduction
In this tutorial we learn how to install crash on Ubuntu 20.04.
What is crash
crash is:
The core analysis suite is a self-contained tool that can be used to investigate either live systems, or multiple different core dump formats including kdump, LKCD, netdump and diskdump.
o The tool is loosely based on the SVR4 crash command, but has been completely integrated with gdb in order to be able to display formatted kernel data structures, disassemble source code, etc.
o The current set of available commands consist of common kernel core analysis tools such as a context-specific stack traces, source code disassembly, kernel variable displays, memory display, dumps of linked-lists, etc. In addition, any gdb command may be entered, which in turn will be passed onto the gdb module for execution.
o There are several commands that delve deeper into specific kernel subsystems, which also serve as templates for kernel developers to create new commands for analysis of a specific area of interest. Adding a new command is a simple affair, and a quick recompile adds it to the command menu.
o The intent is to make the tool independent of Linux version dependencies, building in recognition of major kernel code changes so as to adapt to new kernel versions, while maintaining backwards compatibility.

There are three methods to install crash on Ubuntu 20.04. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install crash Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get update
After updating apt database, We can install crash using apt-get by running the following command:
sudo apt-get -y install crash
Install crash Using apt
Update apt database with apt using the following command.
sudo apt update
After updating apt database, We can install crash using apt by running the following command:
sudo apt -y install crash
Install crash Using aptitude
If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Ubuntu. Update apt database with aptitude using the following command.
sudo aptitude update
After updating apt database, We can install crash using aptitude by running the following command:
sudo aptitude -y install crash
How To Uninstall crash on Ubuntu 20.04
To uninstall only the crash package we can use the following command:
sudo apt-get remove crash
Uninstall crash And Its Dependencies
To uninstall crash and its dependencies that are no longer needed by Ubuntu 20.04, we can use the command below:
sudo apt-get -y autoremove crash
Remove crash Configurations and Data
To remove crash configuration and data from Ubuntu 20.04 we can use the following command:
sudo apt-get -y purge crash
Remove crash configuration, data, and all of its dependencies
We can use the following command to remove crash configurations, data and all of its dependencies, we can use the following command:
sudo apt-get -y autoremove --purge crash
