Add sudo apt-get install texlive-science to latex installation.

\usepackage[ruled,vlined,linesnumbered]{algorithm2e}

Threw error:

! LaTeX Error: File `algorithm2e.sty' not found.Type X to quit or to proceed,or enter new name. (Default extension: sty)Enter file name:! Emergency stop. \usepackage

Which can be resolved with:

sudo apt-get install texlive-science

According to: https://tex.stackexchange.com/questions/46276/package-algorithm2e-on-ubuntu#46277

So include that to the default latex installation and test it.
