Software Installation Model

Best when you need to install, update, or manage software without losing track of trust and repeatability.

Open first lesson

Package Management: GUI Use graphical software centers or app stores to discover, install, update, and remove software more safely than ad hoc downloads. Package Management: CLI Use command-line package managers to search, install, update, and remove software more consistently and with better automation potential. Software Lab: Build a Toolkit Plan and perform a small package-based toolkit setup in a way that is repeatable, reviewable, and safer than ad hoc downloads.

Keep going

Practice right after the lesson while the process still feels fresh.
