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.
A system administrator needs to install a local Debian package file named 'myapp.deb'. Which command should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
rpm -ivh myapp.deb
Why wrong: rpm is for .rpm packages, not .deb.
aptitude install myapp.deb
Why wrong: aptitude, like apt-get, installs from repositories.
dpkg -i myapp.deb
dpkg -i installs a package from a .deb file.
apt-get install myapp.deb
Why wrong: apt-get install expects a package name, not a filename.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
dpkg -i myapp.deb
The correct command to install a local Debian package file is `dpkg -i myapp.deb`. The `dpkg` tool is the low-level package manager for Debian-based systems that directly handles `.deb` files, and the `-i` flag triggers installation. Unlike `apt-get` or `aptitude`, `dpkg` does not resolve dependencies automatically, but it is the proper tool for installing a standalone `.deb` file from disk.
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.
rpm -ivh myapp.deb
Why it's wrong here
rpm is for .rpm packages, not .deb.
aptitude install myapp.deb
Why it's wrong here
aptitude, like apt-get, installs from repositories.
dpkg -i myapp.deb
Why this is correct
dpkg -i installs a package from a .deb file.
Clue confirmation
The clue word "which command" in the question point toward this answer.

apt-get install myapp.deb
Why it's wrong here
apt-get install expects a package name, not a filename.
Common exam traps
The trap here is that candidates confuse `dpkg` with `apt-get` or `aptitude`, assuming that any package manager can install a local file, but only `dpkg` directly handles `.deb` files without requiring a repository lookup.
Detailed technical explanation
Under the hood, `dpkg -i` extracts the control archive and data tarball from the `.deb` file, runs pre-installation scripts, places files according to the package's manifest, and then runs post-installation scripts. A subtle behavior is that `dpkg` does not handle dependencies; if dependencies are missing, the package will be marked as 'unpacked but not configured' until `apt-get install -f` is run to fix them. In real-world scenarios, administrators often use `dpkg -i` for offline installations or custom packages, then follow up with `apt-get install -f` to resolve any dependency gaps.
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.
