headless - Libreoffice convert-to not working

Question

I'm trying to convert documents from html,txt to pdf,odt and vice versa.. But only odt to pdf seems to work.. No other file formats are converted

Here are my commands

libreoffice --headless --convert-to pdf test.html [Not working]
libreoffice --headless --convert-to odt test.html [Not working]
libreoffice --headless --convert-to pdf test.docx [Not working]
libreoffice --headless --convert-to pdf test.odt  [Working]

Answer 1

Try closing all running instances of LibreOffice before executing the command. This was the root cause of my pain.
