How can I view last installed package or program?

Question

Can user list last installed packages by apt-get in terminal?

I need to know which last package I installed on Ubuntu 12.04.

Answer 1

See /var/log/dpkg.log. Or do ...

less /var/log/dpkg.log

It will list all activity regarding packages.

More specific to installation:

grep installed /var/log/dpkg.log

It will list it like this:

2014-01-02 11:20:07 status half-installed libmodule-pluggable-perl 3.6-1
2014-01-02 11:20:07 status half-installed libemail-simple-perl 2.003-1

Answer 2

Rinzwind answered the question well above. If you want to use a GUI, open Synaptic by opening the Ubuntu Dash and typing "Synaptic". You will be prompted for your root password.

When Synaptic is open, go to File --> History. Then select the most recent month and day, and you will be presented with a list of installed, upgraded and removed packages on that day.
