I was trying to get musepack encoder support built into ffmpeg today, and I inadvertently broke a few things but I'm not sure exactly which package I installed which broke them. How can I remove ALL packages I installed today, and start again from scratch more carefully?
I can see a list of them in "Ubuntu Software Center" under today's date in the "History", but I don't want to go through uninstalling them one-by-one, because there are hundreds to do.
Expand the "Installed Software" item in Ubuntu Software Center. You'll see a list of all the different repositories that you've enabled. Clicking on the repo will show you the packages you've installed from each.
If you installed "stuff" via a package manager (apt-get, dpkg, synaptic), it's all logged in /var/log/apt/*. It's a simple matter of editing to generate the apt-get purge commands.
If you installed "stuff" some other way (sudo make install, /usr/bin/cpan, ...) you have to uninstall it using the same method.
To make your life easier in the future, especially if you use the second method, consider installing and using installwatch. From the man page:
trusty (1) installwatch.1.gz
