A new repository has just been added to /etc/apt/sources.list.d. Type the apt-get command, including its subcommand and no other arguments, that refreshes the local package indexes from the configured repositories without installing or upgrading anything.
LPIC-1 Exam 101-500, objective 102. Linux installation and package management easy
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.

apt-get updateapt update
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
apt-get update downloads the Packages and Release files for every entry in /etc/apt/sources.list and /etc/apt/sources.list.d and stores them under /var/lib/apt/lists. Nothing on the system changes apart from that metadata, but until it runs, apt-cache and apt-get still see the old view and will not offer packages from the new repository. Installation and upgrading are separate verbs: install, upgrade and dist-upgrade.
