This LPIC-1 practice question tests your understanding of linux installation and package management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO commands are used to install packages on a Debian-based system? (Choose two.)
pacman -S
Why wrong: This is for Arch Linux.
apt-get install
This installs packages from repositories.
dpkg -i
This installs .deb files.
rpm -i
Why wrong: This is for RPM-based systems.
yum install
Why wrong: This is for RPM-based systems.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
apt-get install
B is correct because `apt-get install` is the standard command-line tool for installing packages from Debian repositories, handling dependencies automatically. C is correct because `dpkg -i` installs a local `.deb` package file directly, though it does not resolve dependencies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
The trap here is that candidates often confuse package managers across distributions, mistakenly associating `rpm` or `yum` with Debian systems due to superficial familiarity with Linux package management.
Detailed technical explanation
`apt-get install` interacts with the APT system, which reads `/etc/apt/sources.list` to fetch packages from remote repositories, resolving dependencies via the dpkg backend. `dpkg -i` directly installs a `.deb` file but will fail if dependencies are unmet, requiring `apt-get install -f` to fix. In real-world scenarios, using `dpkg -i` for a local package without first checking dependencies can lead to a broken system state.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the LPIC-1 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
