LPIC-1 Linux Installation and Package Management Practice Question
A system administrator needs to install a local Debian package file named 'myapp.deb'. Which command should be used?
⚠ Common exam trap
Many 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.

Why each option matters
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.

Option-by-option breakdown
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.
- ✗
apt-get install myapp.deb
