ebook-meta error - "No module named podofo"

[jimrothstein]

I am only trying to change metadata of a .pdf file with ebook-meta

I get this error:
"Unavailable: No module named podofo"


Using ubuntu 10.10; various combinations of the command give same result

jim@jim-laptop:~/Desktop/read-CHINA$ ebook-meta Evergreen.pdf -a NYT -t "EverGreen Solar goes to China"

and I get this result:

Original metadata::
	Title               : Evergreen
	Author(s)           : Unknown
	Book Producer       : cairo 1.7.4 (http://cairographics.org)
Failed to set metadata for u'EverGreen Solar goes to China'
Traceback (most recent call last):

    raise Unavailable(podofo_err)

Changed metadata::
	Title               : Evergreen
	Author(s)           : Unknown
	Book Producer       : cairo 1.7.4 (http://cairographics.org)

Thanks for any thoughts.

Uninstall calibre and use the binary calibre install as described on the calibre website.

Your system is missing the podofo library.
