Error when running Calibre on Nook Touch

[aruangra]

Hello,

I setup the Debian 6.0.0 chroot environment for ARMEL in my Nook Touch. I can use debian packages (for example openssh, lighttpd webserver) successfully. I want to use Calibre to automatically fetch news to the device. So I installed "calibre 0.7.7" using "apt-get install calibre" . It installed a lot of dependencies (400 MB in total).

When I use the command:

ebook-convert nasa.recipe nasa.epub

It started fetching news until the progress at 34% and I got the following errors:

32% Article downloaded: u'NASA Accepting Applications For Aeronautics Scholarships'
33% Article downloaded: u'NASA Earth-Observing Satellite Arrives In California For Launch'
34% Article downloaded: u'NASA Administrator To Kick Off Aviation Forum'

Please suggest me how to solve this problem. Thank you.

Set the LANG environment variable correctly.

Thank you very much. I set the LANG environment variable using the command:

export LANG=en_US.UTF-8

Then I could get the epub file. calibredb also works

The last step is to run the content server. But I got this error:

root@localhost:/usr/share/calibre# calibre-server --with-library /usr/share/calibre/serve/
Traceback (most recent call last):
  File "/usr/bin/calibre-server", line 18, in <module>

  File "/usr/lib/calibre/calibre/library/server/opds.py", line 15, in <module>
    import routes
ImportError: No module named routes

Please advice. Thank you.

You're missing python-routes

The problem is solved. Now, I can run ebook-convert, calibredb, and calibre-server on my Nook Touch. By adding the URL localhost:8080 to Aldiko, I can directly get epubs from Calibre.

The next step is to schedule content download which is not difficult

Thank you very much.
