Install multiple deb files while respecting their dependencies

Topological sort (via script)

The command dpkg -i packages/*.deb is problematic - does not properly respect the order packages should be installed (even if you supply all required packages).

Custom script to rule them all

Under the assumption your debian distro has python installed (mine is ubuntu 14.04 LTS and comes with python27)

Aside the offline .deb packages directory, provide a script that;

• Extract metadata and Topological sorts all candidate packages
• Uses dpkg -i to install the sorted packages in proper order they should be installed

---

For example, execute this command to install all pre-collected offline packages

sudo python install.py

• Your directory structure should look like this

install.py

#!/usr/bin/env python

You can try with -R and install options:

sudo dpkg -R --install dependencies/

-R Recursive handle all regular files matching pattern *.deb found at specific directories and all of its subdirectories
