LFCS Certification Software Package Management 5

Question 1

Which command installs a .deb package and automatically resolves its dependencies from APT repositories?

Accepted Answer

apt install ./package.deb

Answer

Using `apt install ./package.deb` (with the ./ prefix) installs the local .deb file and fetches missing dependencies from repos.

Question 2

What does the `rpm -e --nodeps <package>` command do?

Accepted Answer

Removes a package while ignoring dependency checks

Answer

`rpm -e --nodeps` erases a package without checking whether other packages depend on it, which may break dependencies.

Question 3

In DNF/YUM, what is a 'group' and how do you install one?

Accepted Answer

A collection of related packages installed together with `dnf group install '<name>'`

Answer

DNF groups (like 'Development Tools') bundle related packages for easy bulk installation via `dnf group install`.

Question 4

Which directive in /etc/apt/sources.list specifies that source packages should be available?

Accepted Answer

deb-src

Answer

Lines beginning with `deb-src` in sources.list tell APT where to find source package archives for `apt-get source`.

Question 5

What is the purpose of `rpm --import /path/to/GPG-KEY`?

Accepted Answer

Adds a GPG public key to the RPM keyring for package signature verification

Answer

Importing a GPG key allows RPM to verify the digital signatures of packages signed with the corresponding private key.
