Hi All, I attempted to upload a number of audiobooks to calibre web using the cloudron file manager, as 1-by-1 via the calibre web interface would have been painstakingly slow.

I downloaded /library to my desktop, opened it with calibre locally, added the audio files, then re-uploaded the entire folder (including metadata.db based on advice from previous threads). Things seemed to be working fine and this process was fairly quick, until attempting to fetch metadata on some books which renamed author and/or title. Calibre web threw this error:

Rename title from: '/app/data/library/Betty Smith/A Tree Grows in Brooklyn (154)' to '/app/data/library/Betty Smith/A Tree Grows in Brooklyn (154)' failed with error: [Errno 2] No such file or directory: '/app/data/library/Betty Smith/A Tree Grows in Brooklyn (154)'

When i look in file manager I can see a duplicate folder with different capitalization, and in calibre the book formats/files I had in the older folder are no longer accessible.

I believe this has something to do with permissions of the calibre web user as I'm seeing a similar error to https://github.com/janeczku/calibre-web/issues/637. I thought this might be related to the specific library folder I uploaded so I restored to a previous backup of calibre-web, however (quite unfortunately) the issue still persists now even when using my old un-tampered library.

Anybody have advice on how to fix the permissions of my library folder, or other insights into the source of the issue?
