  1. As it is noted here, it is not intended, even discouraged, to store your Calibre-Library on a network share and access it from different versions across different devices.

    However, with some tweaking, it seems to be possible to get at least Samba shares working when mounted with CIFS. First, ensure that you have the right permissions to the share by specifying the uid option and setting it to 1000 (as was noted in the comment below your post). Then, it looks like also the nobrl option needs to be included as proposed here. (If someone got some insight on this and why this needs to be done, an explanation would be appreciated, I'm just a dumb little end user.) Your final mount-command should look like this:

    mount -t cifs -o username=your_username,password=your_password,uid=1000,nobrl //your_server_name/your_sharename /path/to/your/mountpoint

    I can confirm that this works for me with Calibre Version 3.46.0 on Ubuntu 19.10 x86_64.
