In Ubuntu 20.04.1 LTS x86_64 , LibreOffice Version: 6.4.5.2
I get an error when opening a file:

os.system('libreoffice  --accept="socket,host=localhost,port=2002;urp;" --norestore --nologo	&' )  
time.sleep(3)
desktop = pyoo.Desktop('localhost', 2002)
desktop.open_spreadsheet('myfile.ods')

Error:

  File "./pyoo/pyoo.py", line 1849, in open_spreadsheet
    document = self._open_url(url, extra)

  File "./pyoo/pyoo.py", line 1855, in _open_url
    return self._target.loadComponentFromURL(url, '_blank', 0, extra)
