Any suggestions !!
You have two warnings (marked W) and one error (marked E). One of the warnings and the error refer to PPAs which are not related to the 01.org update tool. The warning that's related to the 01.org repository is telling you you haven't installed the public key used to verify 01.org signatures - instructions for that are on the page which tells you how to download and use the update tool.
Warnings shouldn't stop anything from working, but the error will - you will need to correct the configuration of that PPA (or remove it entirely) before you can proceed.
