Quick Install

git clone https://github.com/YOUR-USER/update-manager.git
cd update-manager

sudo mkdir -p /opt/update-manager
sudo cp update-manager.sh /opt/update-manager/
sudo chmod +x /opt/update-manager/update-manager.sh

sudo ln -s /opt/update-manager/update-manager.sh /usr/local/bin/update-manager

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
cp hosts.conf.example hosts.conf

Edit hosts

nano hosts.conf

Example:

# name        ip              user
server1       192.168.1.10    user
server2       192.168.1.20    user
server3       192.168.1.30    user
