Do you have access to a Windows system? If so, can you install calibre and the extended driver and try this eBook?

It could be because of some sort of error that the plugin is failing to convert to KePub or something to do with your Linux setup or the driver is borked since 3.6.7.

I was using 3.6.9 and reverted to 3.6.7.
edit this book and error checker/epub check came back clear.
I'm already on Windows 11

I'll have to give 3.6.9 a go. I've not sent any KePub to my Libra 2 since 3.6.7.

But at least I know I can go back if need be. Thanks.

I'll post my findings.

If it's of any help for troubleshooting, two ePubs downloaded with FanFicFare success kepubified and uploaded to device without errors.

From the sample ePub posted in the Kepub Output plugin thread, it seems to be an issue with HTML comments ( '<!-- This is a HTML comment -->' ) embedded in the text files.

See message #561 in the KePub Output Plugin thread for the original post

Version 3.6.10 should be offered by calibre within the next hour. This was caused by etree not following their own documentation, which was merry fun trying to chase down. But now there's also a test file including comments.

Thank you very much for the fix. Sorry it was a pain to find out what was going on.

I still get the Not a ZIP file error when i try to upload a PDF to my libra color using v3.6.10.
The same error as with v3.6.9.

calibre, version 7.16.0
ERROR: Error: Error communicating with device

downgrading to 3.6.7 fixes the problem.

Not your fault the lxml folks didn't follow their own documentation!

Can you create a bug on GitHub, include the full calibre debug log, and attach a PDF I can use to reproduce? Not one subject to copyright, if that's all you have I'll have to figure out another way to test a fix.

I created an issue with a debug log and added a PDF that produced the error for me.
Let me know if there is anything else that would help you figure this out.

That you for all the work you are doing!

Found it, I was creating an ePub container before verifying that I actually had an ePub-ish file. Version 3.6.11 should be offered by calibre within the next hour or so.
