On AlmaLinux 10, use `dnf`. AlmaLinux 10 still uses DNF 4, so the HashiCorp/RHEL instructions translate cleanly. RHEL 10 documentation also uses `dnf` for package and repository management. :chatgpt-content-reference{index="0"}

For the Vault Enterprise install shown in your screenshot:

```bash
# Install repository-management tools
sudo dnf install -y dnf-plugins-core

# Add the official HashiCorp RHEL repository
sudo dnf config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo

# Install Vault Enterprise
sudo dnf install -y vault
```

You can verify that the repository was added:

```bash
dnf repolist | grep -i hashicorp
```

And verify Vault:

```bash
vault version
```

So the screenshot effectively becomes:

```text
yum install              → dnf install
yum-config-manager       → dnf config-manager
yum -y install ...       → dnf install -y ...
```
