Good job! But I am inquiring. When I delete a PPA will be deleted and its dependencies? If the answer is “yes”, what happens if those dependencies are used by other PPAs? And they are also deleted? Thank you!
Last tool will delete those or you can simply run:
$ sudo apt-get --purge autoremoveI asked what happens if the dependencies are used by other PPAs? They are erased with erasing that PPA?

Removing a ppa does not remove packages, just the abilty to update any packages you may have installed from that ppa, with system updates.
ppa-purge will disable a ppa and revert installed packages from that ppa to official packages or remove if not official packages.
ppa-purge will prompt before removing or downgrading packages.
Best practice is to use ppa-purge.
It’s up to you to know(find out) if a package is dependant on a particular version of another package from a ppa or if it is compatible with the official downgraded version.
This is a handy one-liner to show installed third party ppas in form that can be used with ppa-purge.
