Select the TWO statements that correctly describe Debian package management on a standard system.
LPIC-1 Exam 101-500, objective 102. Linux installation and package management medium
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.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
The options
Choose 2.
Not correct apt-get update installs all available updates for installed packages
Wrong, and a classic confusion. apt-get update only refreshes the index of what is available; apt-get upgrade is what actually installs newer versions.
Correct The repositories apt downloads from are configured in /etc/apt/sources.list and in files under /etc/apt/sources.list.d/
Correct. Both locations are read; putting third-party repositories in their own file under sources.list.d is the conventional way to keep them separate from the distribution's own entries.
Correct dpkg-reconfigure re-runs a package's debconf configuration questions after it is installed
Correct. It is how you revisit choices such as the timezone (dpkg-reconfigure tzdata) or a package's setup options without reinstalling.
Not correct dpkg resolves and downloads any dependencies a package needs
Wrong. dpkg checks dependencies and refuses to configure a package whose dependencies are unmet, but it never downloads anything — that is apt's job.
Not correct apt-cache can install a package once you have found it
Wrong. apt-cache is strictly a query tool over the package index and makes no changes to the system.
Why
Three separations to hold onto: sources.list plus sources.list.d define where packages come from; update refreshes metadata while upgrade installs; and apt/apt-get resolve dependencies over repositories while dpkg operates on local files and only reports unmet dependencies. dpkg-reconfigure sits on the side, replaying a package's debconf configuration for an already-installed package.
Where this comes from
- Cited
- LPI exam objective 102.4
- What it says
- Debian package tools: dpkg, apt-get, apt-cache, dpkg-reconfigure and /etc/apt/sources.list.
Practise this
Reading one question is not practice. The trainer will draw a short set from objective 102 and space the ones you get wrong.

- A mail server keeps filling its root filesystem because spooled mail and logs grow without bound, and when the disk fills the whole system becomes unusable. Which single change to the disk layout most directly contains that failure? machine-checked

- You are laying out storage for a general-purpose Linux server. Which TWO of the following are genuine reasons to use LVM for the data filesystems rather than plain partitions? machine-checked
- Which file is the configuration file that GRUB 2 generates, and which administrators are told not to edit by hand on a typical Linux distribution? machine-checked
- You replaced the boot disk in a BIOS/MBR system and need to write the GRUB 2 boot loader into the master boot record of /dev/sda, installing the required GRUB modules under /boot. Which command does that? machine-checked
- On a GRUB 2 system whose configuration file is /boot/grub/grub.cfg, type the grub-mkconfig command — including the option and its argument — that regenerates that file. machine-checked
