Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Introduction
The following information concentrates on the latest long-term versions of Debian, Ubuntu and Mint, namely Debian 9 (Stretch), Ubuntu 18.04 (Bionic) and Mint 19.x (Tara, Tessa, Tina, ...), but should be applicable, with modifications, to any Debian-derived distro.
Note that the instructions don't cover the addition or deletion of repositories to/from your software sources. It is intended rather as a diagnostic tool when apt update is generating errors that appear...
The problem
Brackets, the useful web development editor and environment, can be downloaded as a deb archive from http://brackets.io/. However, the package has a dependency on libcurl3, while Ubuntu Bionic and variants, and later versions, use libcurl4. Installing the package will therefore install libcurl3, and remove libcurl4, curl and any packages that depend on these. Not recommended.
This problem has existed for quite some time now, has been reported as an issue several...
This tutorial currently relates to VirtualBox 6.0.x, but will be valid for any version in the VirtualBox repository. The following instructions have been tested on Mint 19.x but should also work on Mint 18.x, Ubuntu 16.04 and 18.04, and other distros based on Ubuntu. Note that since v6, VirtualBox does not support 32-bit hosts, for which you should install VirtualBox v5.2.
The instructions below should not affect any virtual machines you have already set up with a previous version of...
A computer's firmware is low-level software, with an associated data area, that comes pre-installed in flash memory on the motherboard. The first software to be run when the computer is booted, firmware is generally customised to be motherboard-specific and designed to communicate with other hardware in the system. The two main firmware types used nowadays are BIOS and the more recent UEFI. This article does not cover other firmware interfaces such as libreboot and coreboot.
The two main partitioning schemes used on Linux and Windows/DOS are MBR and, more recently, GPT. This article doesn't cover the Mac's original Apple Partition Scheme and additional partition schemes used by various other operating systems.
To understand partitions, it is important to remember that storage devices divide up their space into sectors which are traditionally 512 bytes in length. However, since 2010, most large hard disks (called Advanced Format (AF)) now have physical...
