Packages I need to install for using LaTeX:
sudo apt-get install texlive texlive-latex-extra # TeX Live
sudo apt-get install texlive-lang-german # German (`Package babel Error: Unknown option `ngerman'.`)
sudo apt-get install texlive-bibtex-extra biber # Bibliography
sudo apt-get install texstudio # IDERemark for Debian 8 Jessie: texlive-latex-extra is part of texlive and therefore doesn’t need to be installed. (Installing it anyway makes apt mark it as “installed manually”. This can be undone with apt-mark auto texlive-latex-extra.)
