thanks for your answer,

I have now simply created a new group, which has access to the hard drive and added the Kod-iuser to this group. So everything fits now

BTW: Do you still use lutris? I found a kodi-repo for lutris on github and consider it to give it a try.

That is the add-on I’m using to launch Lutris in Kodi. I have also added the Lutris PPA to my system to have the most recent version. There is a lot of work going into Lutris nowdays.
