Ubuntu: checking what the previous versions of a package that were installed or checking transaction records for apt



Question:

I've got an ubuntu system that was upgraded from 12.04 (I think) to 14.04. I have a bunch of packages that were held, which I had to finesse into working, and a lot of non held packages.

I did the whole shebang - apt-get dist-upgrade, aptitude for reluctant packages, and ended up with a fully updated systems

One of the non held packages (from what looks like an internal mirror of a PPA) is marked as for update, and I'd like to know when, and how the last 2-4 package updates for that happened, and better yet when.

Is there some mechanism in apt for that?


Solution:1

apt is just a front end for dpkg. transactions are recorded in dpkg.log you can get a list of recently installed packages with a terminal with the command zcat -f /var/log/dpkg.log* | grep "\ install\ " | sort which will give you a nicely sorted list with the most recent installation at the bottom or with the GUI by running the System Log application and choosing dpkg.log from the left menu as:
