Find and install LaTeX’s missing packages in Ubuntu.

A lot of search and experiments finally helped me to install the missing packages in LaTeX. It is a bit tedious task to find and install the missing package in Ubuntu.

Let say I have a missing package “titlesec.sty” then the first step is finding the relevant Latex repository.

$ apt-cache search titlesec

shows below line and tells that repository “texlive-latex-extra” contains the missing package,

texlive-latex-extra - TeX Live: LaTeX additional packages

if you want to see all the containing packages you can write command,

$ apt-cache show texlive-latex-extra

install texlive-latex-extra,

$ sudo apt-get install texlive-latex-extra

You are done and now be able to use the package.
