In Ubuntu 18.04 I want to delete all secondary software (all software which isn't drivers or that is required for basic operating of the system).
For example in Ubuntu I want to delete all games, all general usage apps (as for Email), all Amazon apps, the GUI automatic updater, and even the software center manager, etc.
I want to have a super minimal Ubuntu that I would gear up from scratch, per my needs via a script I already prepared.
How could I remove all that software in one go, fast? Thanks.
EDIT --- I need GUI because I love the Ubuntu red-purple-orange-brown GUI.
