I run into the same issue and subsequently found this blog and went through every single suggestion provided so far but was not able to resolve it.
Though, I finally figured it out and share it here in case someone else gets the same trouble. In my case, I only wanted to use "unoconv" on my headless (no X Server) Ubuntu 11.04 (natty) chroot. It took me many many hours. Therefore the sequence of steps outlined below does not reflect what I have gone through but it shows the relevant bits. #Installed "unoconv" $sudo apt-get install unoconv #Run "unoconv" $unoconv -f pdf mytext.txt javaldx: Could not find a Java Runtime Environment! Please ensure that a JVM and the package libreoffice-java-common is installed. If it is already installed then try removing ~/.libreoffice/3/user/config/javasettings_Linux_*.xml Error: Unable to connect or start own listener. Aborting. #I followed the suggestion and installed "libreoffice-java-common" and "openjdk-6-jre-headless". #Run "unoconv" $unoconv -f pdf mytext.txt unoconv: UnoException during conversion: URL seems to be an unsupported one. The provided document cannot be converted to the desired format. #Then I came across this debian bug 491456 discussion and followed the suggestion to install #"libreoffice-writer" "libreoffice-calc" "libreoffice-impress" #Run "unoconv" $unoconv -f pdf mytext.txt Error: Unable to connect or start own listener. Aborting. #Then I learned that (mentioned above in this thread) that the LibreOffice process (soffice) needs to be running. $ soffice Failed to open display #I didn't worry about this much and run the "unoconv" command again $unoconv -f pdf mytext.txt Error: Unable to connect or start own listener. Aborting. #Eventually I figured out that the "soffice" process needs to be started with the "-headless" and "-nofirststartwizard" parameters. http://code.google.com/p/openmeetings/wiki/OpenOfficeConverter Note: Make sure that you kill any previously started "soffice" processes. To check this, run "ps -l | grep soffice". $/usr/lib/libreoffice/program/soffice -headless -nofirststartwizard -accept="socket,host=localhost,port=8100;urp;StarOffice.Service" #Run "unoconv" $unoconv -f pdf mytext.txt Now, it worked. It successfully converted "mytext.txt" to "mytext.pdf". -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
