banish404 | Easy way to remove stale PPAs and Software-Sources

Are you having trouble manually updating PPAs and Software-Sources from your Ubuntu box to solve 404 not founds while updating the system. (I tried banish404 on 13.10).

Issues I'm having while running apt update,
 
Err http://ppa.launchpad.net saucy/main amd64 Packages
  404  Not Found
Err http://ppa.launchpad.net saucy/main i386 Packages
  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

banish404 is a simple tool to automate this hassle.

sudo add-apt-repository ppa:fossfreedom/packagefixes
sudo apt-get update
sudo apt-get install banish404

How to use,

sudo banish404

This will ask for your permission one-by-one to remove stale PPAs and  Software-Sources.More importantly it will back-up your existing sources in to the /etc/apt/ directory.

udara@udara-home:~$ sudo banish404
sources backup folder: /etc/apt/sources_20141210-12:18:33
: 3 3    
checking PPAs...
Disabling /etc/apt/sources.list.d/psyke83-ppa-saucy.list...
Done!
Disabling /etc/apt/sources.list.d/psyke83-ppa-saucy.list...
Done!
checking software sources...

Now if I run apt update, I don't see any 404 not founds.
