Can't read metadata when uploading epub

[scambra]

Expected Behavior

Uploading a epub displays title, author and other metadata available in epub.

Current Behavior

Uploading epub display metadata form empty, only title filled with filename

Environment

OS: Raspbian buster
CPU architecture: arm32
How docker service was installed:
Using dockstarter

Command used to create docker container (run/create/compose/screenshot)

Extract from docker-compose.yml:

  calibreweb:
    container_name: calibreweb
    environment:
    - PGID=${PGID}
    - PUID=${PUID}
    - TZ=${TZ}
    hostname: ${DOCKERHOSTNAME}
    image: linuxserver/calibre-web
    logging:
      driver: json-file
      options:
        max-file: ${DOCKERLOGGING_MAXFILE}
        max-size: ${DOCKERLOGGING_MAXSIZE}
    ports:
    - ${CALIBREWEB_PORT_8083}:8083
    restart: unless-stopped
    volumes:
    - /etc/localtime:/etc/localtime:ro
    - ${DOCKERCONFDIR}/calibreweb:/config
    - ${DOCKERSHAREDDIR}:/shared
    - ${MEDIADIR_BOOKS}:/books

Docker logs

Starting calibreweb displays these errors:

[2020-04-26 19:08:51,707] {/app/calibre-web/cps/book_formats.py:55} WARNING - cannot import epub, extracting epub metadata will not work: libxslt.so.1: cannot open shared object file: No such file or directory

Workaround

Install libxlst1.1 inside docker instance, and restart calbre-web, then uploads extract metadata from epub and displays it in form after uploading file.

@scambra I can't reproduce this with the epubs I've tried. Can you send me an epub to test this with please. Email is my username @linuxserver.io

[scambra]

The errors are print in logs when calibreweb starts. Do you have libxslt1.1? I don't have after pulling docker image, although I installed manually, I can't see libxslt in package_versions.txt

@scambra No I don't have libxlst1.1 but I also can't reproduce the issue with the epubs I've tried, so need something to test with. Trying to work out if this is purely an ARM issue or not.
