Maintain CentOS 8 until 2030, while obtaining the most recent updates from the Navy. With this approach, you will use CentOS 8 as late as 2030 without changing or migrating OS.

Here is how to Maintain CentOS 8 until 2030.

Backup First

Create a backup of your machine before executing.

Remove CentOS repositories

rm -rf /etc/yum.repos.d/Cent*

Install Navy Linux gpg-keys

yum install -y https://cdn.navylinux.org/navylinux/releases/8.5r1/x86_64/os/Packages/navylinux-gpg-keys-8.5r1-121221.noarch.rpm

Setup Release Variables

echo "8" > /etc/dnf/vars/releasever
echo "8" > /etc/yum/vars/releasever
echo "8.5r1" > /etc/yum/vars/releaseversion
echo "8.5r1" > /etc/dnf/vars/releaseversion
uname -i > /etc/yum/vars/infra
uname -i > /etc/dnf/vars/infra

Note: Warning: Only supported on x86_64-based hardware.

Create repositories

curl -o /etc/yum.repos.d/navy-linux-base.repo https://raw.githubusercontent.com/navy-linux/navylinux-release/main/navy-linux-base.repo
curl -o /etc/yum.repos.d/navy-linux-every.repo https://raw.githubusercontent.com/navy-linux/navylinux-release/main/navy-linux-every.repo
