LPIC-1 Linux Installation and Package Management Practice Question

Exhibit

Refer to the exhibit.

$ apt-cache policy apache2
apache2:
  Installed: (none)
  Candidate: 2.4.41-4ubuntu3.5
  Version table:
     2.4.41-4ubuntu3.5 500
        500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages
     2.4.41-4ubuntu3.4 500
        500 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages
     2.4.41-4ubuntu3 500
        500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages

An administrator needs to install apache2 version 2.4.41-4ubuntu3.4 from the security repository to ensure the latest security patches. Based on the exhibit, which command should they use?

⚠ Common exam trap

Many exam-takers confuse the `-t` option (which sets a target release) with the version pinning syntax, or they mistakenly use a space instead of an equals sign when specifying a version, leading to an invalid command.

Answer choices

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

✓

apt-get install apache2=2.4.41-4ubuntu3.4

The `apt-get install apache2=2.4.41-4ubuntu3.4` command explicitly pins the package to the exact version number, ensuring that the specified version from the security repository is installed. This syntax is the standard way to install a specific package version in APT, overriding the default candidate version.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    apt-get install apache2/focal-security

    Why it's wrong here

    This syntax is incorrect for specifying a version. apt does not support a '/' to denote repository; it would be interpreted as a package name including a slash.

  • ✗

    apt-get install -t focal-security apache2

    Why it's wrong here

    The '-t' option sets the target release, but it will install the candidate version from that release, not necessarily the specific version 2.4.41-4ubuntu3.4. The candidate might be a different version in that release.

  • ✗

    apt-get install apache2 2.4.41-4ubuntu3.4

    Why it's wrong here

    This command attempts to install two packages: 'apache2' and '2.4.41-4ubuntu3.4', which is not a valid package name. The correct syntax requires an equals sign between the package name and version.

  • ✓

    apt-get install apache2=2.4.41-4ubuntu3.4

    Why this is correct

    This command correctly specifies the exact version using the '=' syntax, which apt will install from the appropriate repository (security in this case) because the version is present there.
