    I think there may be two bugs hiding here:
    1) latex and dvips are being searched for in the folders /tmp and /usr/share/tuleap/plugins/mediawiki/www, respectively. Placing symbolic links to /usr/bin/latex and /usr/bin/dvips in these folders bypasses this bug.
    2) one or more texlive packages may be missing. After doing step (1) above and editing the mediaWiki page, a *.tex and a *.log file are produced in /tmp. If you open the *.log file, you'll find a complaint about a missing "cancel.sty". I bypassed this bug by doing a complete install of texlive in my machine, and then using symlinks to /usr/local/texlive/2019/bin/x86_64-linux/latex and /usr/local/texlive/2019/bin/x86_64-linux/dvips, instead of /usr/bin/latex and /usr/bin/dvips, in step (1).
    These are crude fixes, but I hope they help you diagnose the problem.
