Solusinya

Jika Anda menggunakan “dnf config-manager –add-repo ” untuk menambahkan repositori, perintah tidak menambahkan konfigurasi lokasi file kunci GPG untuk repositori tersebut. Instalasi paket akan gagal, karena secara default, dnf mengaktifkan gpgcheck. Ini memerlukan kunci GPG untuk disetel atau diimpor.

1. Setel dan impor lokasi file kunci GPG secara manual:

# rpm --import "file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle"

atau

2. Tambahkan atau atur kunci GPG untuk semua entri repositori individual di bawah /etc/yum.repos.d :

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
