Below is the error I am getting when unoconv command is run as apache, with root it works fine.

[root@tux1 apache]# sudo -u apache unoconv -f pdf /var/www/html/testing/example.xlsx

Ok this may be a stupid way to get around it but here goes...

Something in the chain of tools wants a home directory. The user for Apache doesn't have a home directory.

My Apache2 runs as www-data.

So:

mkdir /home/www-data
chown www-data:www-data /home/www-data

Voila! No more errors.

If I were a real geek I would fix the problem further up the tool chain but I'm not so there.

  • I'm using a different user and I'm getting the same error. Can you please help me? – fawad Nov 14 '12 at 14:30
  • Saved my day I was starting to despair about how to generate pdfs on the server with libreoffice headless not working without X and unoconv seemingly not working depending on user?!? Thx so much! – joelhoro Jun 09 '13 at 19:45

I had this error when converting .docx or .doc to HTML using unconv via PHP on Apache:

Error: Unable to connect or start own listener. Aborting.

Eventually, I worked out the issue was with the www-data user not being able tom write to its home folder (in my case at /var/www). I fixed the permissions and the error was sorted.

i have added .config and .cache sub-folders with www-data user permissions and kept the root on /var/www/ https://stackoverflow.com/a/70891861/8187662
