I had problems running the TeXLive package manager tlmgr on my Ubuntu 16.04 LTS install. Apparently the package manager changed formats in 2016, so the version that is included with Ubuntu is out of date (and presumably so is TeX/LaTeX).
Luckily, there’s a repo with the latest TeX as described here: tipsonubuntu.com/2016/09/16/install-tex-live-2016-ubuntu-16-04-14-04/
In short, if you have TeX already installed, do this:
sudo add-apt-repository ppa:jonathonf/texlive sudo apt update; sudo apt upgrade
After that you’ll run into the following bug: bugs.debian.org/cgi-bin/bugreport.cgi?bug=824137 You’ll need to do the following to get around it: sudo apt -f remove texlive-base texlive-fonts-recommended texlive-latex-extra texlive-latex-recommended texlive-pictures texlive-pstricks texlive-base-bin prosper texlive-fonts-recommended-doc texlive-fonts-extra-doc texlive-latex-base texlive-generic-recommended texlive-latex-base-doc texlive-latex-extra-doc texlive-latex-recommended-doc texlive-pictures-doc texlive-pstricks-doc tipa sudo apt install texlive-base texlive-fonts-recommended texlive-latex-extra texlive-latex-recommended texlive-pictures texlive-pstricks texlive-base-bin prosper texlive-fonts-recommended-doc texlive-fonts-extra-doc texlive-latex-base texlive-generic-recommended texlive-latex-base-doc texlive-latex-extra-doc texlive-latex-recommended-doc texlive-pictures-doc texlive-pstricks-doc tipa
After that, you should be running the latest TexLive.
