SSH Setup (Required)

Update Manager uses SSH to connect to your hosts.

You must have SSH key-based authentication set up (no password prompts).

Generate SSH key (if not already done)

ssh-keygen -t ed25519

---

Copy key to hosts

ssh-copy-id user@192.168.1.10
ssh-copy-id user@192.168.1.20
ssh-copy-id user@192.168.1.30

---

Test connection

ssh user@192.168.1.10

You should be able to connect without entering a password.

⚠️ If SSH is not configured, the tool will fail or hang during execution.

Configuration

Copy config files

cp update-manager.conf.example update-manager.conf
