Removing a package while keeping configuration | LPIC-1 101-500 Exam original practice question

102.4Basic

Remove the installed nginx package with APT.

Keep its package configuration files by using remove rather than purge.

Which command is appropriate?

Hint 1: Focus on the requirement

Identify what must change and what must remain unchanged. Then choose the command whose scope matches that requirement.

Hint 2: Check each command's role

Separate commands that display information, change state, remove data, or affect a child process.

apt-get purge nginx: Incorrect. purge requests removal of the package's configuration files too.
apt-get remove nginx: Correct. apt-get remove nginx removes nginx while normally keeping its configuration.
apt-cache remove nginx: Incorrect. apt-cache is for querying package indexes.
apt-get clean nginx: Incorrect. apt-get clean removes cached archives and does not take a package name here.
