Below you can find the most common installation packages for LaTeX and their approximate disk space requirements based on Ubuntu 20.04 with minimal installation selected: • texlive-base – 160 MB • texlive-latex-recommended – 203 MB • texlive – 269 MB • texlive-latex-extra – 464 MB • texlive-full – 5903 MB The first package texlive-base will install just the basics to get you started with LaTeX. texlive or texlive-latex-extra is most likely the best way to get started for most users. However, our package selection is only motivated by the requirement for the least disk space consumed after the LaTeX installation. If you have plenty of space and a good download speed nothing stops you to go for texlive-full package. But be aware that this package will fetch the whole lot, including, but not limited to, eg. Japanese language pack. Furthermore, Ubuntu offers more profession targeted package selections such as: • texlive-publishers • texlive-science • texlive-pstricks • texlive-pictures • texlive-metapost • texlive-music • texlive-xetex • texlive-luatex • texlive-games • texlive-humanities 1. Regardless of your package choice you can install LaTeX by use of the apt command. The following linux command will install the LaTeX package: texlive-latex-extra. Replace the package name with the one you wish to install, open up terminal and enter: $ sudo apt install texlive-latex-extra


That is all.

2. Now, that we have LaTeX installed let’s just confirm the installation by compiling a simple LaTeX code.Open up any text editor like for example gedit, enter the following code and save as hello-world.tex:
\documentclass{article}
\usepackage{hyperref}
\begin{document}
Hello world \LaTeX

\url{https://linuxconfig.org}
\end{document}


Once you have the above LaTeX code saved use the pdflatex command to compile it to PDF. If the pdflatex command is available on your system you will need to install texlive-extra-utils before you can use it:

$pdflatex hello-world.tex  3. The above step will compile your hello-world.tex to hello-world.pdf. Next, start Evince PDF viewer to see the result: $ evince hello-world.pdf

4. Compiled Latex document
5. (optional) Install a LateX editor and compiler for an easy LateX document editing and compilation.
