If you use Linux, you can open Debian DEB files using the Debian Package Management System or Synaptic Package Manager. You can also use Adept, which is an open source graphical interface for working with package management.
If the DEB file extension is a Debug Script file, you can open this type of DEB file using Notepad or WordPad for Windows, Apple TextEdit for Mac, or gEdit and Nano Editor for Linux.
DEB files created by Cydia must be opened by the Cydia program which uses its own applications. Cydia basically acts as its own App Store offering applications that are downloadable after you jailbreak your iPhone. For this reason, you must open this type of DEB program using Cydia on an iOS device.
