  • Add a local (file) repository to the package manager
  • Install an exact package version and hold it
  • Verify installed package files and restore a modified one

Start this lab

With the CLI installed and signed in, this command provisions a fresh Ubuntu 24.04 LTS virtual machine on your Mac, applies the scenario setup and prints the task below.

goldenkube start lfcs-ops-004

Task

The task text exactly as the CLI shows it. Solve it on the machine, then run goldenkube submit.

A package repository has been prepared in /srv/repo (flat layout: the Packages index sits directly in that directory; it is not signed). It carries gk-tools 1.0 and 1.1 and lab-config 1.0. 1. Configure the package manager to use it, then install version 1.0 of the package gk-tools from it. Make sure gk-tools stays at 1.0 during future upgrades. 2. The installed package lab-config has one file that was modified after it was installed. Use the package manager's verification to find it, write the file's absolute path to /root/modified-file.txt, then restore the original file from the package.
