Unable to export calibre library

Midge · 05-05-2025, 07:26 AM

The following error pops up:

calibre, version 8.3.0
ERROR: Failed: Failed to export data. Click "Show details" for more information.

Traceback (most recent call last):
File "calibre\gui2\dialogs\exim.py", line 156, in run_action
File "calibre\utils\exim.py", line 213, in export
File "calibre\db\cache.py", line 85, in call_func_with_lock
File "calibre\db\cache.py", line 3179, in export_library

File "calibre\db\backend.py", line 1856, in copy_format_to
File "shutil.py", line 197, in copyfileobj
OSError: [Errno 22] Invalid argument

Apologies if the answer is obvious. I'm a bit thick.

Are you trying to export to some funky location like a network drive or similar?

Midge · 05-05-2025, 01:02 PM

Initially yes, but after the first failure I figured that was probably the problem so I tried exporting locally and the same message popped up.

That error is basically the windows kernel telling calibre it cant open a file, either because the export location or the calibre library itself are in some funky location.

I am having the exact same issue. The library is not in any funky location. Both the library and the intended backup folder is in my home directory. I am running Arch Linux and Calibre 8.4. Any chance I can get a hand with that, please?

You cant possibly be getting the exact same issueona different OS. Post the actual traceback.

That's a disk full error. Either the target locationis full or you have /tmp mounted on a ramdisk and its full.
