Ошибка при генерации epub

[Zavyalov]

Генерация epub на Ubuntu 16.04.6 LTS требует ключа -o:
pandoc -t epub -o faif-2.0.epub faif-2.0.tex

А сейчас так:

cp faif-2.0.pdf faif-2.0-v0.99.7.pdf
pandoc -t fb2 faif-2.0.tex > faif-2.0.fb2
cp faif-2.0.fb2 faif-2.0-v0.99.7.fb2
pandoc -t epub faif-2.0.tex > faif-2.0.epub
pandoc: Cannot write epub output to stdout.
Specify an output file using the -o option.
Makefile:12: recipe for target 'epub' failed
make: *** [epub] Error 5
