Solution is re-install at least one add-on which has this dependency and than all start to work…

The add-on developer should declare these dependencies correctly.

But it seems, that he did:

<import addon="script.module.simplejson" version="2.0.10" />

and second addon:
<import addon="script.module.simplejson"/>

But I don’t know if that version matters

You may just have to install those scripts from the repository manually. I upgraded this evening and that was the only thing of mine that didn’t work correctly. Went into the repository, installed those scripts (mine were actually different scripts as I guess I was using a different addon) and then it was working ok.

I couldn’t find that simplejson module in repo so i made it this way. How to find system modules in repo?
