Apt-get key deprecated

I m trying to download lutris on kali linux and im getting this:
└─$ wget -q https://download.opensuse.org/repositories/home:/strycore/Debian_9.0/Release.key -O- | sudo apt-key add -
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
gpg: δε βρέθηκαν έγκυρα OpenPGP δεδομένα.
(no valid OpenPGP data found)
What can i do ?


wget -O- https://download.opensuse.org/repositories/home:/strycore/Debian_10/Release.key | gpg --dearmor | sudo tee /usr/share/keyrings/lutris-archive-keyring.gpg

see here https://www.linuxuprising.com/2021/01/apt-key-is-deprecated-how-to-add.html

or you can probably still use apt-key Debian_9.0 was 404
