Problems adding Epub

arti47 · 07-11-2022, 03:33 AM

I'm having difficulty adding a new epub to my library after updating to 6.0.

I get this error:
calibre, version 6.0.0
ERROR: Cannot add books: Failed to add some books, click "Show details" for more information.

Worker process crashed while executing job
Traceback (most recent call last):
File "calibre/utils/ipc/pool.py", line 108, in recv
File "calibre/utils/ipc/__init__.py", line 24, in eintr_retry_call

File "multiprocessing/connection.py", line 419, in _recv_bytes
File "multiprocessing/connection.py", line 388, in _recv
EOFError

Anyone has this problem too?

Something is blocking calibre worker processes on your computer, most likely an antivirus. Try adding calibre.exe and calibre_parallel.exe to the antivirus exclusion list or temporarily disable the antivirus to see if that is indeed the cause.

even for me, same error message. I use a Mac (MacOs Monterey) without any antivirus...

kovidgoyal · 07-11-2022, 05:03 AM

What version of macOS is this? And run calibre in debug mode and post the log there may be more information there. In the Preferences menu choose restart in debug mode.

I have the exact same problem on MacOS Monterey since installing version 6.0. Here's the content of my debug log:

Same here, no antivirus.

I am able to add AZW3, but not EPUB.

kovidgoyal · 07-11-2022, 07:36 AM

This will be an issue with the dedrm plugin go to preferences->plugins and disable that plugin and you should be fine.

uninstalling dedrm makes Claibre 6 accept epub again!!
on Mac (Catalina)

thanks

Unfortunately, disabling / uninstalling DeDRM means that Calibre can't accept books with DRM. It seems there's an issue either with Calibre v6, DeDRM (v10.0.2) or something with the way the two are working together.

Anyone have a solution for continuing to use DeDRM with Calibre (other than rolling back to a previous version of Calibre)?

DeDRM (v10.0.2) is working for me running Linux Mint 20.3 Cinnamon. There is a fix for QT6 in the github master.

https://github.com/noDRM/DeDRM_tools

clink on the code button download zip.

Edit7/12/2022:
unzip the zip file then run make_release.py to make DeDRM_tools.zip, unzip then follow calibre instution for installing plugin from file.

You don't have to uninstall it. You can disable it and re-enable as needed.

Thanks. I'm on MacOS Monterey (12.4) and haven't seen anything related to a fix for that.

Remember, you will NOT get auto- notification of 'tools' updates. Only those shown in Get Plugins section have notifications.

You need to check where you got them (or the successor).
Usually, there are comments about updates (that is really all MR rules permit) in some forums here.

My apologies if this has been posted before, or if this isn't the proper forum, or any number of other issues...

Getting an error importing non-DRM books:

"calibre, version 6.0.0
ERROR: Critical failure: The read metadata worker process crashed while processing some files. Adding of books is aborted. Click "Show details" to see which files caused the problem."

Occurrs on all of the ePubs I attempt to import.

Any assistance you can provide would be appreciated.

If you'd read the entire thread, you'd have seen that the problem is with DeDRM on MacOS. You will need to disable DeDRM for now.
