Seperti yang Anda semua tahu, CentOS 8 telah mencapai EOL-nya pada 31 Desember 2021, saatnya untuk meningkatkan CentOS 8 Linux Anda ke CentOS Stream, yang merupakan masa depan Proyek CentOS. CentOS telah mengalihkan fokusnya dari CentOS ke aliran CentOS, yang merupakan aliran tengah antara Fedora dan RHEL. Jika Anda berencana untuk mengupgrade CentOS 7 ke CentOS 8, maka lebih baik untuk melewatkan upgrade ke CentOS 8 karena CentOS 7 akan mendapatkan dukungan hingga 2024! Jika tidak dapat dihindari untuk meningkatkan, maka tingkatkan ke CentOS Stream seperti di bawah ini:
Langkah 1: Perbarui CentOS 8 Anda ke rilis terbaru
# dnf update -y
Langkah 2: Periksa versi OS
# more /etc/redhat-release CentOS Linux release 8.5.2111
Langkah 3: Perbarui ke paket rilis CentOS Stream terbaru. Ini membuat sistem Anda mencari repo CentOS Stream daripada repo CentOS 8.

Langkah 4: Sinkronkan paket yang diinstal ke versi terbaru yang tersedia.
# dnf distro-sync -y
Langkah 5: Validasi rilis OS
# more /etc/redhat-release CentOS Stream release 8
Itu dia! Khawatir tentang masa pakai CentOS Stream? Kemudian beralih ke distribusi lain seperti Rocky Linux, AlmaLinux, atau Oracle Linux yang menyediakan LONG TERM SUPPORT (LTS).
Di sisi lain, menginstal CentOS 8 dan terjebak dengan kesalahan "Gagal mengunduh metadata untuk repo"? Ini solusinya.
