Hi, with an up to date TL, `lwarpmk' is not found: ┌──── │ $ lwarpmk html │ zsh: command not found: lwarpmk └──── but running: ┌──── │ /usr/local/texlive/2016/bin/i386-linux/lwarpmk html └──── works like a charm. Hence the trouble is, `lwarpmk' is missing in `/usr/local/bin/'. All the best. -- Denis
