I'm getting a 404 on the namniart URL as well. @ahendrix?

That's funny.. it's trying to retrieve Release.In, when the filename should probably be InRelease. I'll do a little digging and see if I can figure out why that's happening.

Scratch that; it was just a formatting error in the question.

Is apt getting a 404 error on that URL, or a different error? Please edit your question to include the full error message.

Are you using a soft-float (armel) or hard-float (armhf) version of Ubuntu?(soft-float is no longer supported).

Were you able to retrieve the apt key in the previous step properly? If you weren't, there's probably something wrong with your network connection. If you were able to retrieve the apt key, then you may want to make sure that you don't have a typo in your sources.list.

EDIT

It looks like you're trying to use armel (soft-floating point EABI), which is no longer supported, and doesn't perform very well anyway. You should upgrade to an armhf version of Ubuntu.

Thanks.It helped me a lot indeed.But is there a way can installing ros on the armhf version of Ubuntu.

The instructions for installing an armhf version of Ubuntu on your board will depend on which board you're using.

If I use the armel version of ubuntu go on.Can I install ros from source on arm according to this page http://wiki.ros.org/groovy/Installati...

Alice63 ( 2014-10-30 07:01:53 -0500 )edit

It's possible to do a from-source build on armel, but it takes a few days to run the compilation, and there will be packages like PCL that can't be compiled because some boards don't have enough RAM.

ahendrix ( 2014-10-30 11:33:25 -0500 )edit

Your time will be better spent finding and installing an armhf version of Ubuntu or Linaro.
