Hi and welcome to the forum :slight_smile:
You need to set a FQDN rather than the default one (linux-j9oy) via YaST Network Settings for the hostname warning.

For the media one, if you have the online repositories (as in registered the system) available, you can disable this repo, else you would need to leave the media in since it’s looking for it.

Suggest you register the system and make sure it’s all up to date and then review your messages.
