Hi,
I am using the converter ,
I have installed openoffice3

openofffice path : /opt/openoffice.org3/program/python
my unoconv is in my projects root directory and i created a doctopdf text file and run that file using exec() form a function in my project.
The content of doctopdf text file is as follows

directory=$1
filename=$2
extension=$3
SERVICE='soffice'
if [ "ps ax|grep -v grep|grep -c $SERVICE" -lt 1 ]; then
unset DISPLAY
/opt/openoffice.org3/program ./soffice.bin -headless -accept="socket,host=127.0.0.1,port=2002;urp;" -nofirststartwizard -display 0.0 &
sleep 5s
fi
/opt/openoffice.org3/program/python unoconv -f $directory$filename.pdf $directory$filename.$extension

But am getting the error
Error: Unable to connect or start own listener. Aborting.

Please help
Thanks in advance

I would suggest using a newer LibreOffice release and use the latest unoconv, or the one from the master branch !

Please feel free to reopen if your issue is still pertinent.

I got same error in php, but I solved problem with 'running a unoconv listener', and It refer to Kopz Kyoto's answer

launch a unoconv listener
sudo unoconv --listener

do transcode by call unoconv
unoconv -f docx file.doc

when i execute the same command in terminal or using python to execute, it's ok.
I guess: my php is called by apache2 which belongs to www-data group, so it hasn't permission to call LibreOffice(unoconv will call LibreOffice to transcode), so there are some ways to solve the prblem:

1. grant permission to LibreOffice so that it can be called by which source process from www-data group;
2. launch a unoconv listener process to receive transcode request (Kopz Kyoto's answer, i preference this way).
