I am getting below error when I try to update. I had gone through the previous articles related to this question but none of them were helpless. Could you please help me to rectify this?

W: Failed to fetch  Unable to find expected entry  contrib/binary-i386/Packages in Meta-index file (malformed Release file?)

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

The contents of /etc/apt/sources.list are

cat /etc/apt/sources.list # (deleted commented lines and deb-src)
deb lucid main restricted
deb lucid-updates main restricted
deb lucid universe multiverse
deb lucid-updates multiverse

Regards, Raj

could you include your /etc/apt/sources.list and the output of ls -l /etc/apt/sources.list.d? – qbi Jan 8 '13 at 10:55

Lot of restrictions to "Add Comment" :( – Raj Jan 8 '13 at 11:09

Cloudera offers a step-by-step tutorial for the installation. As far as I can tell from your comments you did everything as described there. However Cloudera only offers packages for 64Bit architecture. As your system tries to download i386 packages I assume you are running on 32Bit. In this case it is not possible to use this software.

However if you are running 64Bit you download the deb and then run manually sudo dkpg -i cdh4-repository_1.0_all.deb. This will install the recent version on your system (but only in the 64Bit case).

You are correct. I am running on 32Bit. I will try the same on 64Bit and let you know my findings. thanks a lot! :) – Raj Jan 8 '13 at 11:42
