"Nepomuk Semantic Desktop needs the Virtuoso RDF server to store its data."

[Shaved Wookie]

Binary package hint: kdebase

Since updating to KDE 4.4 Beta 1, my previously working nepomuk now just spits out the following notification when I log in / try to enable nepomuk:

Nepomuk Semantic Desktop needs the Virtuoso RDF server to store its data. Installing the Virtuoso Soprano plugin is mandatory for using Nepomuk.

I have all packages with soprano in their name (other than -doc -dbg and -cli) installed. I've tried clearing ~/.kde/share/apps/nepomuk and this happens both in Karmic and Lucid.

I filed upstream, and Sebastian Trueg (Nepomuk maintainer) said that Virtuoso Server needed to be installed, although this doesn't seem to exist in the repositories.

I'm trying this on two systems Kubuntu Karmic AMD 64 and Kubuntu Lucid AMD64. Both are running KDE 4.4 Beta 2 packages (and had the same problem with Beta 1).

This also happens with KDE 4.4 Beta 2

We know that, we are waiting also Debian for Virtuoso 6.0.1 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=508048
Patience patience :)

Status changed to 'Confirmed' because the bug affects multiple users.
