Hi,
Thanks for the response.
After some testing this seems to have been an issue with the container and/or configuration. After deleting the entire config folder & using the image: lscr.io/linuxserver/calibre:arm64v8-arch-version-02a2ceb8 (Calibre version 5.38) the autostart works as expected. This version uses the autostart:
s6-envdir -fn -- /var/run/s6/container_environment /usr/bin/calibre $CLI_ARGS
After some further testing with more recent versions (anything later than Calibre 5.38). All containers seem to have the same problem with Openbox giving the error: “Error launching startup command: Failed to close file descriptor for child process (Operation not permitted)”
Someone already opened an issue GitHub:
https://github.com/linuxserver/docker-calibre/issues/82
This problem seems to occur in other linuxserver docker containers as well (also using the baseimage-rdesktop-web:arch).
I’ll watch the issue on GitHub for a possible solution. Thanks for now.
