Cloudera Hadoop - install error

Question

I'm new to Linux and Hadoop. I want to learn the basics of Pig, MapReduce and Hive and I'm trying to install Cloudera's Hadoop solution on Ubuntu. This is the tutorial I'm following. I'm stuck on Step 1. I'm not using a proxy, so I skipped the proxy configuration steps. Got to step 1.6, and then I get the following error message. Any ideas what I should try?

Refreshing repository metadata failed. See /var/log/cloudera-manager-installer/2.refresh-repo.log for details. Click OK to revert this installation.

And this is what's on that log file:

Answer 1

Looks like you have broken repository references that are unrelated to Cloudera, but causing your install to fail.
