I'm sorry I have added libnss3 to the container so not sure how I can help... I don't really know calibre-web

[alexbelgium]

Actually it is already in the container : https://github.com/linuxserver/docker-calibre-web/blob/984876c8c9cc42c88d82e77d0f88382c76ddbd47/Dockerfile#L23

You could post in the linuxserver github https://github.com/linuxserver/docker-calibre-web as they are the ones providing the base image

I'm sorry I can't help you if the linuxserver github's tells you what we need to change I'll implement that

[pbvdven]

[alexbelgium]
