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

Could someone Assist me in this matter. This is urgent. Thanks

Can you please post the contents of your /etc/apt/sources.list file. I have a feeling you're missing the "deb" that must begin each repo. So your for example should have,
also you are using "etch" which is not the current stable version of debian. I suggest you change "etch" to "lenny" (or better to "stable") in the above mentioned file.
cheers,

what jdkaye said, except that switching to lenny unprepared is not recommended.
