Prepare for the Linux+ XK0-006 exam (CompTIA Linux+ V8). In this lesson: package managers (dnf, apt, rpm, dpkg, zypper), repositories, GPG signatures and exclusions, other ways to install (Flatpak, pip, cargo, npm, source code), update-alternatives, and common services: DNS, NTP and chrony, DHCP, web servers, and mail, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.
