The answer is that the repository's Release file has not been regenerated after adding the new package. APT relies on the Release file to verify the current state of the repository’s metadata; when you run apt-get update, it downloads this file to learn which package versions are available. If the Release file still references the old metadata for version 1.0, APT will not see the new version 2.0, even though the .deb file is physically present. On the LPIC-1 exam, this tests your understanding of APT’s repository structure and the critical role of metadata files in package management—a common trap is assuming that simply copying a package file into the pool directory is enough. Remember the mnemonic: “No Release, no peace”—without a regenerated Release file, APT remains stuck on the old version.
LPIC-1 Linux Installation and Package Management Practice Question
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 company maintains a private Debian repository for internal packages. A new package 'internal-tool' version 2.0 has been added to the repository, but when users run 'apt-get update && apt-get install internal-tool', the old version 1.0 is still being offered. What is the most likely cause?

Correct answer & explanation
✓
The repository's Release file has not been regenerated after adding the new package
The most likely cause is that the repository's Release file has not been regenerated after adding the new package. APT relies on the Release file (and its associated InRelease or Release.gpg) to obtain the current package metadata, including version information. If the Release file is not updated to reflect the new package version 2.0, APT will still see the old metadata and offer version 1.0, even though the package file exists in the repository.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The package version number is not higher than the installed version
Why it's wrong here
Version 2.0 > 1.0.
✗
The local apt cache needs to be cleared with 'apt-get clean'
Why it's wrong here
clean removes .deb files, not the package index.
✗
The 'apt-get update' command did not run successfully due to network issues
Why it's wrong here
Network issues would produce an error message.
✓
The repository's Release file has not been regenerated after adding the new package
Why this is correct
apt uses the Release file to check validity; if outdated, it may ignore new Packages files.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume the problem is with the local client cache (option B) or network issues (option C), when the real issue is a server-side metadata synchronization failure that prevents APT from discovering the new package version.
Detailed technical explanation
How to think about this question
APT uses a three-step metadata chain: the Release file (signed with GPG) lists checksums for Packages files, which in turn list package versions and dependencies. When a new package is added to a repository, the repository maintainer must regenerate the Packages file (e.g., using 'dpkg-scanpackages' or 'apt-ftparchive') and then update the Release file with new checksums and timestamps. Without this regeneration, APT's 'apt-get update' downloads the unchanged Release file, so the client's metadata remains stale, and the new package is invisible. In a private Debian repository, this is a common oversight when packages are added manually or via scripts that forget to run the metadata update step.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.

About these practice questions
Courseiva creates original exam-style practice questions with explanations and wrong-answer analysis. It does not publish real exam questions, exam dumps, or protected exam content. Learn why practice questions differ from exam dumps →
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which THREE of the following are valid methods to install a package from a local .deb file?
hard
A.alien -i package.deb
B.rpm -i package.deb
✓ C.gdebi package.deb
✓ D.dpkg -i package.deb
✓ E.apt-get install ./package.deb
Why C: 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.
