Maintaining Package Installation Logs in Debian

Where does the Debian package manager write entries for actions taken and packages installed?

a. /var/log/apt/history.log

b. /etc/debian/pkglog

c. /usr/bin/dpkg.log

d. /var/aptitude/logfile

The log file where the Debian package manager writes entries for actions taken and packages installed is option c: /usr/bin/dpkg.log

Debian package manager, apt, maintains a log file named /usr/bin/dpkg.log that records all actions taken by the package manager, including installations, updates, and removals of packages. This log file is essential for tracking the history of package management on a Debian system.

/var/log/apt/history.log is not the correct option as it is the log file for apt history, which maintains a record of all the packages installed, upgraded, and removed using apt-get or apt commands. This log can provide insights into package management activities.

/etc/debian/pkglog is not the log file used by the Debian package manager. This directory contains package information files and not the log of package manager actions.

/var/aptitude/logfile is the log file for the aptitude package manager, which is a graphical front-end for apt. It is important to note that aptitude uses a different log file compared to the apt package manager.
