Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I try to install FBReader via Ununtu Software Center, but it stalls for a long time and even after the process is supposedly complete, Ubuntu doesn't display epub and mobi files when I click them. It says "There is no application installed for “Mobipocket e-book” files. Do you want to search for an application to open this file?" and this process doesn't finish. What should I do?

Alternatively, I need something to display epub/mobi files.

My internet connection is ok; e.g. I am able to install system via ubuntu netinstall without a problem.

calibre Install calibreInstall via the software center


calibre is a free and open source e-book library management application developed by users of e-books for users of e-books.

Calibre is primarily a ebook cataloging program. It manages your ebook collection for you. It is designed around the concept of the logical book, i.e. a single entry in the database that may correspond to ebooks in several formats. It also upports conversion from a dozen different ebook formats to LRF and EPUB. A graphical interface to the conversion software can be accessed easily by just clicking the "Convert E-books" button.

Supported input formats are: MOBI, AZW, LIT, PRC, EPUB, ODT, HTML, CBR, CBZ, RTF, TXT, PDF and LRS.

Starting calibre's ebook viewer as a standalone application

In certain cases you will not want to add an epub or mobi file to calibre's library before reading it. Luckily calibre's ebook viewer can be started independently via ebook-viewer. This makes it possible to create a standalone launcher:

#!/usr/bin/env xdg-open
[Desktop Entry]
Exec=ebook-viewer %f
Name=Ebook Viewer
Comment=Display .epub files and other e-reader formats

See here for more information on adding launchers to your system.

To click an ebook and open in ebook-viewer, make this application (usr/bin/ebook-viewer) the default for that type of file.

Will Calibre work as a simple ebook viewer, too? e.g. I want to open ebook by double-clicking it, check it out and not add to my library or download to my e-reader device. I guess, with Ubuntu installing from repositories should generally work just fine? Just installed it; seems to work. But when I double-click an ebook, it still goes "There is no application installed for “Mobipocket e-book” files. Do you want to search for an application to open this file?" – Nickolai Leschov Aug 4 '13 at 12:02
I select "Open With" but where is "Add button"? If you meant "Other Application", there's no option to point to this file, too. – Nickolai Leschov Aug 4 '13 at 12:29

No, "Other Application" puts me into this… then this… Will look into additional information, thanks. – Nickolai Leschov Aug 4 '13 at 14:40

Try this. If you use Firefox browser, you can install EPUB Reader from its Add-On manager.

Do you mean I could install an add-on like this? It works, but I would prefer a native ebook reader application in my system. – Nickolai Leschov Aug 4 '13 at 11:52
