Failed to start loolwsd

[alex1452]

Dear all,

I have installed Kopano LibreOffice Online from the repository on Devuan 9.0 (ascii), which is Debian without systemd in a privileged LXC container. Installation was without problems. Since I cannot use the systemd-start script, I tried to start loolwsd for testing purposes manually with the command inside the systemd script:

sudo -u lool /usr/bin/loolwsd --version --o:sys_template_path=/opt/lool/systemplate --o:lo_template_path=/opt/libreoffice5.4 --o:child_root_path=/opt/lool/child-roots --o:file_server_root_path=/usr/share/libreoffice-online

Unfortunately I get the following errors:

The first line is because I have disable SSL according to the documentation. I have also confirmed that the filesystem supports suid. I have added the suggested option to grub.cfg:

linux /boot/vmlinuz root=PARTUUID=ea0b2a87-02 rootfstype=ext4 rootwait acpi_enforce_resources=lax file_caps=1 console=tty0 console=ttyS0,115200n8 noinitrd

Any idea what I can do to solve this error?
