Installing/Adding new latex packages in ubuntu environment

Been using ubuntu for a while, here I made some notes on how to add/install new latex packages..

A. If the package in the sty format

1. create a new directory under tex tree

–> sudo mkdir /usr/share/texmf-texlive/tex/latex/<packagename>

2. copy the package inside the new directory

3, run the following command

–> sudo mktexlsr

B. if the package is not the sty format

1. Download <packagename>.ins and <packagename>.dtx (you need both)

2. Run the following command

–> latex  <packagename>.ins

3. You will get the package in the sty format and you can follow instructions in A.

I hope this helps. Thanks to this page.
