I found them!
Thank you so mush !

I doubt logs are gonna help any.

The "beta" and "demo" campaigns no longer exist in 0.17. It seems like the factorio's internal-updater is not fully removing them. Resulting in the "beta" folder still existing after the update to 0.17 but the "description.json" file was removed.

Browsing out to ...

Updated installation linux gives me
File __base__/campaigns/beta/description.json not found (No such file or directory)

Guess I can fix it from the download, but you should know that this happened.

Edit: I don't think downloading 1,1Gig of full game is worth one json file, can I get it ...
