How can I uninstall the last installed application (recently installed) with dpkg?

I need to use a command and or script that uninstalls the last recently installed application deb . I can't use apt-get in this case but rather dpkg --purge or similar, something like dpkg --remove (last recently installed application) but without providing the name of the application.

thanks

ls -tl /var/lib/dpkg/info/*.list | head -n 1 | awk '{print $8}' | xargs -n1 basename | sed -e "s/.list//"

ls -tl /var/lib/dpkg/info/*.list : gives you the list of package sorted by date

head -n 1 : gives you the first item

awk '{print $8}' : gives you the fullpath filename

xargs -n1 basename : gives the filename , like curl.list

sed -e "s/.list//" | gives you the package name

Finding the last installed package is relatively simple. It's the newest entry in /var/lib/pkg/info.

However, uninstalling that will not necessarily restore the system to its prior state.

Installing a package will also install all of its dependencies. So, to really undo the install you also need to undo those dependencies. You can see that 'libfoo' was updated around the same time as 'appbar'. However, the info files will not tell if the previous state was no 'libfoo', or just an older version of 'libfoo'.
