However, you can use the arrows and pages keys on the keyboard to cycle and run previously typed commands. You can check the Debian/Ubuntu Logrotate configuration for dpkg by using cat /etc/logrotate.d/dpkg.The only caveat with this tool is that you can view your current history, but you can't select the command like using the F7 key. This is because by default on Debian, Ubuntu and Linux Mint, the dpkg log is set to rotate once a month, keeping 12 old logs (so for 12 months), and compress rotated files by using gzip (. Want to go back even more in the dpkg history? Use zgrep instead of grep, and read /var/log/dpkg.log.2.gz, /var/log/dpkg.log.3.gz, /var/log/dpkg.log.4.gz and so on, which go back two, three and respectively four months. For example to see the package installation history for the previous month, use: For the previous month, read the /var/log/dpkg.log.1 log file.

var/log/dpkg.log contains the package install, update and remove history for the current month.
Show a history of recently removed packages and the date / time they were removed, on Debian, Ubuntu or Linux Mint:
Windows bash grep to search history upgrade#
12:31:12 upgrade chromium-codecs-ffmpeg-extra:amd64. 12:31:08 upgrade chromium-browser:amd64. 12:31:04 upgrade chromium-browser-l10n:all. 12:31:04 upgrade chromium-chromedriver:amd64. Show a list of recently upgraded packages, the date / time they were upgraded, as well as the old and new package version, on Debian, Ubuntu or Linux Mint: Show a history of recently installed packages, their version number, and the date / time they were installed on Debian, Ubuntu or Linux Mint: Similarly, the /var/log/apt/history.log APT log file only lists actions performed using apt/ apt-get.

For example, Synaptic Package Manager ( File -> History) can only show a history of installed, upgraded or removed software packages for which Synaptic itself was used to perform those actions, but you won't see any packages installed, updated or removed from the command line (using apt, apt-get, dpkg), using the Software Updater, or the Software application.
Some alternative ways of showing the package manager history on Debian, Ubuntu or Linux Mint, do not display a complete log. It does not work for other packages, like Flatpak or Snap, or for software installed from source, and so on. This works for DEB packages installed in any way, be it using a graphical tool such as Synaptic, Gnome Software, Update Manager, or a command line tool like apt, apt-get, aptitude or dpkg. You can use grep to parse this file from the command line and only display installed, upgraded or removed packages, depending on what you need. To be able to get a complete history list of package changes, including installed, upgraded or removed DEB packages, and show the date on which a particular action was performed, in Debian or Ubuntu, one can read the dpkg (the low-level infrastructure for handling the installation and removal of Debian software packages) log available at /var/log/dpkg.log.
