I personally use TexWorks for creating and editing TEX documents. I also often use IEEEtran.cls package along with many other related scientific packages, such as subfig, etc. This post will go over how to install these packages successfully in the Ubuntu environment.
First off, add the TexWorks repository
$ sudo add-apt-repository ppa:texworks/stable -y
Install TexWorks and lots of latex-related packages that are frequently used
$ sudo apt-get install -y texworks texlive-fonts-recommended texlive texlive-latex-extra texlive-math-extra texlive-pstricks texlive-science latex-beamer
Download IEEEtran.zip file from http://www.ctan.org/tex-archive/macros/latex/contrib/IEEEtran/ by
$ wget http://mirrors.ctan.org/macros/latex/contrib/IEEEtran.zip
Unzip the file to the latex package location
$ sudo unzip IEEEtran.zip -d /usr/share/texmf/tex/latex/IEEE
Let tex know that the package has been added manually
$ sudo texhash
Now, you should be able to run TexWorks and compile TEX files!
