Linux FAQs with Answers--How to remove PPA repository from command line on Ubuntu
Question: I added a third-party PPA repository on my Ubuntu box some time ago. How can I remove the PPA repository?
A Personal Package Archives (PPA) is a Ubuntu way to allow independent developers and contributors to build and distribute any custom packages as a third-party APT repository via Launchpad. If you are a Ubuntu user, chances are that you have added some popular third-party PPA repositories to your Ubuntu system. If you want to remove any pre-configured PPA repository, here is how to do it.
Suppose you have a third-party PPA repository named "ppa:webapps/preview" added on your Ubuntu system, as follows.
$ sudo add-apt-repository ppa:webapps/preview
If you want to delete a PPA repository alone, run the following command.
$ sudo add-apt-repository --remove ppa:someppa/ppa
Note that the above command does not touch any packages installed or upgraded from the PPA itself.
If you want to delete a PPA repository as well as all packages installed/upgraded from the PPA, you can use ppa-purge command.
To install ppa-purge package:
$ sudo apt-get install ppa-purge
To remove a PPA repository and all its packages from the command line:
$ sudo ppa-purge ppa:webapps/preview
These methods can be useful when you identify and purge broken PPA repositories（注：此文原文在同一个更新中，文件名：“20140915 Linux FAQs with Answers--How to find and remove obsolete PPA repositories on Ubuntu.md”） after distro upgrade.
