I would like to know where I can find the logs for the following package managers:
- Synaptic Package Manager
- Ubuntu Software Center
- The logs when using the terminal with
apt-get

Apt logs can be found in /var/log/apt/term.log. To view them with GEdit you can use the command:
gedit /var/log/apt/term.logI like /var/log/apt/history.log. It is very concise.
Also note that older logs are archived with logrotate once a month. To combine the current history.log and all the older compressed history.log files you can use cat and zcat like this:
cd /var/log/apt && cat history.log > ~/Desktop/allhistory.log && zcat history.log*gz >> ~/Desktop/allhistory.log && cd
Then you can, for example, use grep to find what you need:
$ grep package_name ~/Desktop/allhistory.log where you will put what you want in place of package_name.
$ grep google ~/Desktop/allhistory.log

Upgrade: google-chrome-stable:amd64 (30.0.1599.101-1, 31.0.1650.48-1)And, Bohr, in a comment, suggested using zgrep directly if one is searching for lines related to a specific package. This works for me assuming I'm searching both history.log and its existing archived files for smtube:
zgrep smtube /var/log/apt/history*check the file
/var/log/dpkg.logwhich records all the apt activities, such as installs or upgrades, for the various package managers
also you can view synaptic logs through its gui
You can use:
zcat /var/log/dpkg.log.*.gz | cat - /var/log/dpkg.logor if you want less details:
zcat /var/log/dpkg.log.*.gz | cat - /var/log/dpkg.log | grep -E 'install |upgrade |remove '
