For reference, we don't support anything to do with SuperRepo here - it's on our banned_add-on (wiki) list because of some of the addons ...

Ok, thank you for this information.
As I wrote, I'm a new user, and have no Kodi background knowledge.
I discover this really useful Media center.

I only use it for
My pictures
My music (I did encode all my 33, 45, cds, even old 98rpm from my gramophone.
My own family vidéos

I've scanned all covers of my dvds and bluerays. This is why I install this pictures database addon.

Following your answer, I remove the superrepo. repository
Thanks for helping.
