so the archwiki explains that zathura needs the package zathura-pdf-mupdf for EPUB support.

And this askubuntu thread seems to confirm it works on Ubuntu too.

So I have installed the package thanks to the PPA mentioned in the askubuntu post :

user@host :~/Downloads/test $ > dpkg -s zathura-pdf-mupdf | grep Status
Status: install ok installed

user@host :~/Downloads/test $ > zathura --version
zathura 0.4.3
girara 0.3.2 (runtime: 0.3.2)
(plugin) pdf-mupdf (0.3.4) (/usr/lib/x86_64-linux-gnu/zathura/libpdf-mupdf.so)

And downloaded an example .epub file "Alice in Wonderland" from here.

As you can see below, the file seems to be correctly recognized as an EPUB by my system (as listed here) :

user@host :~/Downloads/test $ > xdg-mime query filetype aliceDynamic.epub 
application/epub+zip

However, zathura looks like it doesn't recognize it as such, and is unable to read the file, even with the zathura-pdf-mupdf package :

user@host :~/Downloads/test $ > zathura aliceDynamic.epub 
error: Unknown file type: 'application/zip'

Do you know what could be the issue ?

  • Ubuntu 18.04

  • Are you running a terminal from within Emacs? It would be worth trying to open your EPUB from a regular terminal (gnome terminal, etc.).

  • No, this is only an indicator in the prompt that readline is in Emacs mode (the default, which you are on if you have not set -o vi)

From https://en.wikipedia.org/wiki/EPUB epub file is a zip archive with many files inside . This is a very common design choice , example JAR files are also a zip file .

A solution to fix , is to convert the adobe file EPUB to a EPUB that is readable by zathura .

I tested with calibre , so you need :

  • import the adobe version into the calibre library
  • convert
  • save to disk

or

  • look in the folder Calibre Library in you home dir

you will a epub file and the original epub

This solution was tested on Ubuntu 18.04 lts with same packages you propose .

  • Can you explain what is this supposed to be changing ? How would zathura behave better with this "new epub" ? What is the rationale behind it ? My zathura can't read any epub as is (I tested several files). Or is it just an empirical law you just happened to come across ?

  • @MarianMinar So you will come to "brag" that it works for you but not give a single information on your system ? Do you understand what stackexchange is supposed to be ?
