If we are using libreoffice in headless, with a non root user, trying to convert files with libreoffice, we will get error:
root@amd:~# sudo -u www-data php -r "exec(\"/usr/bin/libreoffice --headless --convert-to pdf '/home/app.tutorialspots.com/public_html/admin/data/downloads/reservation-64.docx' --outdir '/home/app.tutorialspots.com/public_html/admin/data/downloads/'\");" javaldx failed! Warning: failed to read path from javaldx LibreOffice 7.3 - Fatal Error: The application cannot be started. User installation could not be completed.
Check in HOME directory of the user, example we use user www-data, HOME directory is /var/www
Find folder .config, if this folder isn’t exists, we must create it
In folder .config, we find folder libreoffice, if this folder isn’t exists, we must create it
Now run this command:
chown -R www-data:www-data /var/www
