Grails installation error: Err http://ppa.launchpad.net saucy/main amd64 Packages 404 Not Found [duplicate]

I have tried installing Grails using the answer found at Error Installing Grails - Unmet Dependencies :

sudo add-apt-repository ppa:groovy-dev/grails
sudo apt-get update
sudo apt-get install grails-ppa

The first command returns without errors:

$ sudo add-apt-repository ppa:groovy-dev/grails Grails is an advanced and innovative open source web application platform that ... More info:

OK

But the update command fails:

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

Any idea why the ppa update fails with a 404 error?

Ubuntu 13.10 is no longer supported because it reached its end of life.
You should upgrade to 14.04 or use 12.04, the currently supported LTS versions, to get the newest (security) upgrades.

You are getting the 404 error because the ppa is no longer maintained, most likely because the eol of 13.10.
