I might be able to help but these dockbook situations can be confusing
first) you have to have DocBook-XML-DTD and DocBook-XSL-Stylesheets
the problem right now is the DTD part
so look in /usr/share/xml/docbook
mine says
Code:
xml-dtd-4.3 xsl-stylesheets-1.66.1
you most likely have that stuff already so the problem is in versions
you most likely don't have to upgrade anything just trick dockbook like this
go to the folder /etc/xml
open the file "docbook"
there you find redirects from these network files to your local files
here is example from mine
you have to figure out the exact path to the one you have and redirect seeks on
"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd"
to what you have
there is a long 3 part way to do this and a short 1 part way i show the short one
put this at the bottom of the file before the closing </catalog> and of course adjust if your actual version or path is different than mine
Code:
<rewriteURI uriStartString="http://www.oasis-open.org/docbook/xml/4.2" rewritePrefix="file:///usr/share/xml/docbook/xml-dtd-4.3"/>
