whenever i try install any PPA package this error is displayed:

E: GPG error: http://ppa.launchpad.net saucy InRelease: Clearsigned file isn't valid, got 'NODATA' (does the network require authentication?)

this happens whenever i add any PPA repository, after which none of the apt-get commands (that require internet connection) work. but when i uncheck or remove all the PPA repositories from Software & Updates>>Other Software, everything just works fine.
i need to install some PPA packages but i am not able to.

 please tell me how to fix this problem...

[abbas (syedmohdabbasmehdi)]

i found the solution.
the sun-java 7u25 was messing up with my system.
when i removed java, everything is just working fine.
