@davidfor,
I just updated this plugin today. I am now getting this error message when I use
Edit metadata > Download cover
Code:
calibre, version 3.34.0
ERROR: Download failed: Failed to download any covers, click "Show details" for details.
Traceback (most recent call last):
File "site-packages\calibre\utils\ipc\simple_worker.py", line 289, in main
File "site-packages\calibre\ebooks\metadata\sources\worker.py", line 132, in single_covers
WindowsError: [Error 183] Cannot create a file when that file already exists: u'D:\\sysfiles\\calibre\\caltemp\\calibre_95odki\\rjfrcf_single_metadata_download\\Kobo Books,,1368,,2100,,jpeg.cover.done'
Despite the error message, many covers are fetched - including one labelled Kobo Books - and double-clicking one of them pulls it into calibre in the normal way.
