Cover thumbnails not being generated when books are imported from calibredb #3149

Closed wonx closed 2 months ago

Describe the bug/problem

I usually import books by placing them in a folder and using calibredb to add them to my database. Something like this: /app/calibre/calibredb add --with-library=/books /books_to_import

However, this last time, all the books it imported are missing their cover. The cover.jpg file on each folder is missing.

To Reproduce

Steps to reproduce the behavior:

  1. Access calibre-web from a console
  2. run /app/calibre/calibredb add --with-library=/books /books_to_import
  3. Wait for the process to finish.
  4. Open calibre-web on a web browser. The covers will be missing

Ok, I was able to fix the issue. For anyone else experiencing the same, there are 3 libraries that are needed. They can be installed with:

apt install libegl1 libxkbcommon-x11-0 libopengl0
