Linux Package Management 3

Question 1

Which command removes a package along with its configuration files on Debian-based systems?

Accepted Answer

apt-get purge

Answer

`apt-get purge` removes the package and its configuration files, whereas `remove` leaves config files behind.

Question 2

In RPM, what does the `Epoch` field in a package's NEVRA (Name-Epoch-Version-Release-Architecture) override?

Accepted Answer

The version comparison order

Answer

The Epoch field overrides version comparison, so a package with a higher Epoch is always considered newer regardless of version numbers.

Question 3

Which file would you edit to pin an APT package to a specific version on Ubuntu?

Accepted Answer

/etc/apt/preferences

Answer

`/etc/apt/preferences` (or files in `/etc/apt/preferences.d/`) is used for APT pinning to control which versions are installed.

Question 4

What does `flatpak update` do without specifying a package name?

Accepted Answer

Updates all installed Flatpak applications

Answer

Running `flatpak update` without arguments updates all installed Flatpak applications and runtimes.

Question 5

How do you list only manually installed packages (not auto-installed dependencies) with `apt`?

Accepted Answer

apt-mark showmanual

Answer

`apt-mark showmanual` lists packages that were explicitly installed by the user rather than pulled in automatically as dependencies.
