Ubuntu and all other distributions from the Debian ecosystem use the package manager apt instead of yum.
Therefore, you can find its logs inside the directory /var/log/apt.
Most important is the history.log file in that location, which briefly logs all package operations (installed, upgraded, removed packages...). The other one is term.log, which logs the complete terminal output of all apt invocations.
Note that due to log rotation, old log files will be regularly (about once per month) compressed and renamed by appending an index number (and the compression ending .gz), so that the highest number indicates the oldest compressed log. Example: history.log.3.gz
On Ubuntu the high-level package manager is APT. There's a directory
/var/log/aptwhich containswhich lists APT commands, who ran them, and what was installed, upgraded or removed.
and
which logs the output of APT commands.
The lower level package manager is
dpkg. In the fileYou can see package status updates made by

dpkg.log.1or a.gzfile (readable withzless) - these are older logs./var/log/aptcontains the log entries concerning packages installed byapton Ubuntu.There are two sets of entries,
