Bug#674692: libnepomuk4: Nepomuk complains about missing virtuoso server resp. virtuoso
I just ran into the same problem when uninstalling virtuoso.
After
sudo apt-get install virtuoso-vad-rdfmappers
the message about the virtuso RDF plugin missing disappeared.
Hence virtuoso-vad-rdfmappers seems to contain the missing dependencies.
This message marked as wontfix seems to be a duplicate: #671391,
As the problem is recurring it should be fixed.
In 671391 the following reason is given for not fixing:
"kde-runtime has already a recommend on virtuoso, and it's more than
enough given that
a) any KDE application depend on kde-runtime
b) the semantic desktop is an *optional* feature
So no, an hard dependency will *not* be added."
If the semantic desktop is optional and depends on virtuoso,
uninstalling virtuoso should disable the semantic desktop in a
consistent way.
Uninstalling libnepomuk4 will remove 150+ packages like kwrite and ark.
So if the semantic desktop is optional and depends on virtuosol
libnepomuk4 may not be the right place to put the dependency.
A package "semantic desktop" with the appropriate post-remove script
might be more helpful.
Why does Nepomuk show a warning at all if an optional feature is not
installed?
