By default, the package with the highest version number is installed, regardless of which repository it comes from, unless its version number is lower than the currently installed version of the package (this can happen, for example, if you downloaded a higher version as a .deb package and installed it manually).

You need to look into the list files. For instance, I have a java ppa. The list is webupd8team-java-trusty.list.

I've already faced similar problems and I figured that in most cases the only thing you have to do is sudo dpkg --configure -a and then sudo apt-get install -f If that doesn't help, you should edit file /var/lib/dpkg/status and delete whole blocks of broken packages. Then repeat first two commands and that's it.

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, ...

The command to remove an apt repository is apt-add-repository with the -r option which will remove instead of add the repository. So in your case, the full command would be: sudo add-apt-repository -r ppa:colingille/freshlight The other option is to look in /etc/apt/sources.list and /etc/apt/sources.d/ and remove it from there.
