Error installing the Knowledge Bases.

[omarsmak]

Hello,

I was trying to run a DBepdia server using this command:

java -jar kbox-v0.0.1-alpha3-RC16.jar -server -kb http://dbpedia.org/3.9/en/full -install

But I got the following error:

WARNING: Closing storage with uncommited data, this data will be discarded.
Error installing the Knowledge Bases.

Thought it only worked with one KB : http://linkedmdb.org

We are back, thanks for your feedback and sorry for the inconvenience.
We were replicating our servers.
From now, our users will experience more reliability.

Thanks a lot :). Just a question, which KB URL that is referring to DBpedia 2016-04?

[edgardmarx]

DBpedia 2016 is beta.
It already has many beta versions and it would be difficult to say exactly which version is available.
By now I also suggest you to not use it.
However, It will be available as soon as DBpedia have a stable release version.

The issue is still persisting, perhaps the jar distribution file is not updated?

[edgardmarx]

Are you trying http://dbpedia.org/3.9/en/full?
What is the error?
Can you copy paste here?
I would like to know if it is after or before derreferencing.
If install is in 100% than it is not the derreferencing, otherwise, you will have another error.

This is the error:

root@kbox:~/ubuntu# java -jar kbox-v0.0.1-alpha3-RC16.jar -server -kb "http://dbpedia.org/2015_10/en/full" -install
Loading Model...
Error installing the Knowledge Bases.

Same goes for one of the examples:

root@kbox:~/ubuntu# java -jar kbox-v0.0.1-alpha3-RC16.jar -sparql "Select (count(distinct ?s) as ?n) where {?s ?p ?o}" -kb "https://www.w3.org/2000/01/rdf-schema,http://xmlns.com/foaf/0.1" -install

Error exectuting query 'Select (count(distinct ?s) as ?n) where {?s ?p ?o}': null

I noticed that you updated table.kns yesterday, perhaps you need recompile the final executable jar file?

[edgardmarx]

Cool, it seems you do not have internet access, check it out and let me know...

[omarsmak]

What does that mean? This is from the VM:

root@kbox:~/ubuntu# ping www.google.com

Ummm, it means you are the lucky one :)...

I am receiving this:

java -jar kbox-v0.0.1-alpha3-RC16.jar -kb http://dbpedia.org/3.9/en/full -install
Installing KB http://dbpedia.org/3.9/en/full
Installing 0% [> ] 0/100, ETA: N/A

So it means you have an error before.
Can you check if you have read/write access in kbox resource folder.

Try to listing it:

https://github.com/AKSW/KBox#listing-the-resource-folder

And change it:

https://github.com/AKSW/KBox#changing-the-resource-folder

Waiting...

I tried the the same one as yours and it worked:

java -jar kbox-v0.0.1-alpha3-RC16.jar -server -kb http://dbpedia.org/3.9/en/full -install
Loading Model...
Installing   0% [>                    ]   0/100, ETA: N/A^Croot@kbox:~/ubuntu# ^C

But with another version of DBpedia, the same error:

java -jar kbox-v0.0.1-alpha3-RC16.jar -server -kb http://dbpedia.org/2015-10/en -install
Loading Model...
