I'm sure I am overlooking something, but after scouring the dpkg documentation, I cannot find the options that tell me a list of all packages that are installed on my system and the time/date on which they were installed and/or updated.
What I am looking for is something similar to rpm -qa, but for Debian- based Ubuntu systems, and also with some date information for each package (such as an installation log).
For finding out the date of installation of any package, I just look at the timestamp of the corresponding .list file in /var/lib/dpkg/info.
dpkg-www can show you a list of packages installed in the last <n> days. -- Raj Kiran Grandhi
