i found on the internet there is also a netinstaller.
I read you should use the fedora server. I did that and took xfce because only the base and when everything was installed I wanted to install an icon theme. he asked me during the installation if I want to import a gpg key. I wanted to ask if it was secure or not. is only pure to try because with this method I get a clean xfce like a workstation.
that’s at the terminal
GPG-KEY 0x3C3359C4 is imported
User-ID: Fedora (31) firstname.lastname@example.org
