Virtuoso 6.1 upgrade crashes nepomuk

[doctordruidphd]

Binary package hint: virtuoso-opensource-6.1

System: kubuntu lucid 10.04, all current updates applied.

BEFORE the upgrade:
I have virtuoso-opensource-6.0 installed. When I start the system, the version of virtuoso-t installed by virtuoso-nepomuk loads, and nepomuk runs properly. To use the virtuoso datbases, I kill virtuoso, then re-run it from the virtuoso-opensource directory, and virtuoso works properly, but nepomuk does not. This is the "normal" behavior.

AFTER the upgrade:
Problem: After applying the upgrade to virtuoso-opensource-6.1 that is currently available from the repositories, the virtuoso-opensource server starts on bootup -- conductor is available. However, all of my databases, passwords, etc have been removed.
Also, nepomuk fails to work. After logging in to kde, I get an error box saying:

-----------------------------------
Nepomuk Indexing Agents Have Been Disabled
The Nepomuk service is not available or fully operational and attempts to rectify this have failed. Therefore indexing of all data stored in the Akonadi PIM service has been disabled, which will severely limit the capabilities of any application using this data.

The following problems were detected:
Calling the Nepomuk storage service failed: 'The name org.kde.NepomukStorage was not provided by any .service files'.
Additional help can be found here: userbase.kde.org/Akonadi

-----------------------------------

If I try to start strigi fom SystemSettings > Desktop Search, I get an error box saying:

-----------------------------------
Nepomuk Indexing Agents Have Been Disabled
The Nepomuk service is not available or fully operational and attempts to rectify this have failed. Therefore indexing of all data stored in the Akonadi PIM service has been disabled, which will severely limit the capabilities of any application using this data.

The following problems were detected:
Nepomuk is not running.
Additional help can be found here: userbase.kde.org/Akonadi
-----------------------------------

In both cases, akonadi is still running.
Searching from Dolphin does not work.

Killing and restarting nepomukserver from the terminal produces this:

--------------------------------------

I still have a backup version of the system prior to the upgrade, and a version after the upgrade, so I can work on both.

Possible fix:

Remove the file
 ~/.kde/share/apps/nepomuk/repository/main/data/virtuosobackend/soprano-virtuoso.trx
Evidently this is not compatible with the new virtuoso-t.
Also removed
/var/lib/virtuoso-opensource-6.1/db

Lost all the data, but I lost all that upgrading from 6.0 -> 6.1 anyway.

Rebooted, now nepomuk works, and virtuoso conductor works. There are two virtuoso processes, one for nepomuk and another for the regular database, and both seem to be coexisting.

Works in both Maverick and Lucid.

Another possible fix:

stop nepomuk

Remove the file
~/.kde/share/apps/nepomuk/repository/main/data/virtuosobackend/soprano-virtuoso.trx

restart nepomuk

It worked for me without data loss

@jefferson159: Seems this "fix" worked for me too. Thank you :-)
