Unoserver ran once and don't restart

[classifaddict]

Hello,
I succeed running unoserver/unoconverter once and then I never been able to start the server again after rebooting the machine:

$ sudo unoserver --daemon --executable /usr/lib/libreoffice/program/soffice.bin
INFO:unoserver:Starting unoserver.

This happened in both Ubuntu 20.04.3 WSL and Virtualbox.

Is there anything that could prevent unoserver from restarting?

Thanks for this tools and your help!

Try without --daemon and see what happens. Maybe it crashes?

[classifaddict]

$ sudo unoserver --executable /usr/lib/libreoffice/program/soffice.bin
[sudo] password for olivier:
INFO:unoserver:Starting unoserver.
INFO:unoserver:Command: /usr/lib/libreoffice/program/soffice.bin --headless --invisible --nocrashreport --nodefault --nologo --nofirststartwizard --norestore -env:UserInstallation=file:///tmp/tmp8ip81ibp --accept=socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;StarOffice.ComponentContext
$

Is there a log file somewhere?

[regebro]

No, Libreoffice is very bad at logging. As a last attempt, try just running libreoffice. It seems it doesn't start properly.

[classifaddict]

unoconvert is OK if I run this command in a separate shell:
/usr/lib/libreoffice/program/soffice.bin --headless --invisible --nocrashreport --nodefault --nologo --nofirststartwizard --norestore -env:UserInstallation=file:///tmp/tmp8ip81ibp --accept="socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;StarOffice.ComponentContext"

[regebro]

Since that is literally all Unoserver does, I can't explain that.

[classifaddict]

Weird! I will let you know if I find an explanation.
Thanks.

Had the same problem, solved by doing:

$ unoserver --daemon --executable /usr/lib/libreoffice/program/soffice

Please note it's not soffice.bin, and please don't start it with sudo!

Then unoconvert worked. Tested in a python virtual env.

Normally unoserver just calls libreoffice, but unless you have a broken install somewhere, that would be /usr/lib/libreoffice, which is a symlink to /usr/lib/libreoffice/program/soffice, so I'm curious to why --executable /usr/lib/libreoffice/program/soffice would make a difference.

Yes it works too without specifying the executable.
I specified that in case the OP needs it.

[regebro]

True, they specified soffice.bin, I'll try to remember that if somebody else has this issue to see if that makes a difference.
