Kaliyug, can you file an issue at issues.sonatype.org under the NEXUS
project?

There are two things I would suggest here:

We do not support the "register" operation as it's not required for Nexus. You do not need to register a package since it's not the same as the main PyPI repository, i.e. you don't have to worry about someone else taking the package name, as that kind of access control to authorized parties should happen based on who has the proper roles within Nexus. (We have discussed having a more specific error message in the logs relating to this, since it's not necessarily obvious unless you read the documentation.)
If you encounter any problems with the "upload" operation (skipping over the "register" operation), it's quite possible you're encountering a problem relating to https://bugs.python.org/issue10510 which was fixed in later Python 2.7 releases. I would suggest upgrading to the latest 2.7 release if issues are encountered with the upload operation.

I am an absolute beginner to Python and Nexus :)

Hosting several PyPI repositories as shown below:

Let's consider the repos. python-packaging

My inputs on the reply:

Ok, I will then simply skip the 'register' part
As mentioned in my original post, the 'upload' works fine, it's the 'pip install' when the issues are encountered

I have raised a JIRA ticket for the same.

Got it! I didn't see those as they were hidden by my email client and I didn't notice to click to expand.

My thoughts on those issues:

For the "pip search" command that seems to be failing, you're using the wrong URL. Instead of http://l5111t.sss.se.com:8081/repository/python-packaging/ you would want to use http://l5111t.sss.se.com:8081/repository/python-packaging/pypi instead.
For the "pip install" command I think you're also using the wrong URL. Instead of http://l5111t.sss.se.com:8081/repository/python-packaging/ you want http://l5111t.sss.se.com:8081/repository/python-packaging/simple instead.

I would refer to the Nexus 3 PyPI documentation at https://help.sonatype.com/display/NXRM3/PyPI+Repositories, particularly the parts about configuring a local pip.conf as that will be directly applicable to determining the proper URLs for a particular repo.

Yeah, I figured that out:

I used the URL specified 'The URL used to access this repository' in the repository's settings shown in the Nexus UI. It was only after I browsed through this part of documentation that I realized that one needs to append a 'simple' at the end of the repository URL. The command that worked:

pip install --index-url http://l5111t.sss.se.com:8081/repository/python-packaging/simple python-packaging --trusted-host l5111t.sss.se.com -vvv
