CBZ to PDF AttributeError

Pannette · 09-26-2021, 11:52 AM

Hi all, I've been using Calibre frequently to convert CBZs (which Calibre automatically converts from .zips) to PDFs, but for some reason some files have started giving me trouble despite not making any changes to my conversion parameters. Any thoughts? Unfortunately I'm not a CS person so I'm pretty bad at making heads or tails of this.

Opena bug report and attach one of these cbz files, as far as I can tell this is caused by a change in pyqt but I need the file to verify.

This should fix it, but I need a test file to be sure: https://github.com/kovidgoyal/calibr...0c1222ff55adc9

Oh my, you replied so quickly! Yes, I'll get on that asap.

EDIT: File attached. It's called 1.zip.

How should I go about adding this change? Also, not sure if my post got eaten or if it's just waiting for mod approval, but I did in fact attach the file via a bug report.

You do NOT attach unscrambled files here (MR). Use the Bug reporting tool (link at)

Sorry, yes - I did submit a bug report already. Apologies for being unclear.

Either run calibre from source, or wait for next release in a couple of weeks.

FWIW: if I don't want the 'book' in calibre I use a no-frills program called "CBR_and_CBZ_to_PDF". You could use it as an interim solution.
