LPIC-1 Linux Installation and Package Management Practice Question
A technician needs to add the official Debian repository for the 'buster' release. Which line should be added to /etc/apt/sources.list?
⚠ Common exam trap
It's easy for candidates to confuse the 'deb' and 'deb-src' prefixes, or mistakenly add '-updates' thinking it is required for the base release, when the question specifically asks for the repository line for the 'buster' release itself, not its updates.

Correct answer & explanation
✓
`deb http://deb.debian.org/debian buster main`
It uses the standard 'deb' prefix for binary packages, points to the official Debian repository at http://deb.debian.org/debian, specifies the release codename 'buster', and includes the required component 'main'. This is the exact format required by APT to fetch packages for the Debian buster release.
