This LPIC-1 practice question tests your understanding of linux installation and package management. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 THREE of the following are valid methods to install a package from a local .deb file?
alien -i package.deb
Why wrong: Alien converts to .rpm first.
rpm -i package.deb
Why wrong: rpm does not handle .deb files.
gdebi package.deb
gdebi handles dependencies.
dpkg -i package.deb
Direct installation.
apt-get install ./package.deb
apt can install local .deb files.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
gdebi package.deb
C is correct because `gdebi` is a dedicated tool for installing local `.deb` packages while automatically resolving and fetching their dependencies from configured repositories. It provides a safer alternative to `dpkg` when dependency handling is required.
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.
alien -i package.deb
Why it's wrong here
Alien converts to .rpm first.
rpm -i package.deb
Why it's wrong here
rpm does not handle .deb files.
gdebi package.deb
Why this is correct
gdebi handles dependencies.

Common exam traps
The trap here is that candidates may think `rpm` can handle .deb files due to a superficial similarity in package management commands, or that `alien` is a primary installation tool rather than a format converter.
Detailed technical explanation
Under the hood, `dpkg -i` extracts the package archive and runs pre/post-installation scripts but does not resolve dependencies, which can lead to a broken state if dependencies are missing. `gdebi` wraps `dpkg` and uses APT's dependency resolution to automatically install required packages from repositories, making it ideal for offline or local installations where dependency chains must be satisfied. In real-world scenarios, administrators often use `gdebi` for installing proprietary .deb files (e.g., Google Chrome) to avoid manual dependency hunting.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
