If you are unable to convert some documents, ensure first that you have installed the appropriate LibreOffice package. For example, if you want to convert a text document, you need libreoffice-writer. If you want to convert a spreadsheet, you need libreoffice-calc. On most installations, unoconv will pull "libreoffice" package that contains everything needed. However, this is only a suggestion and if you have configured your package system to not install suggestions, you need to install the appropriate modules by hand. If this still does not work, check that you are able to open the document using LibreOffice. -- Vincent Bernat , Sat, 5 Mar 2011 12:37:43 +0100
