Prerequisites

Before starting, make sure you have administrator privileges and a stable internet connection. Additionally, you need to install Rust since Topgrade is written in this language.

Step 1: Install Rust

Update the system and install the necessary dependencies:

sudo apt update
sudo apt install -y curl build-essential pkg-config libssl-dev

Download and install Rust using the official script:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Add the Cargo directory to the PATH for the root user:

echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.profile
source ~/.profile

Verify the installation of Rust and Cargo:
```
rustc --version
cargo --version
```

Step 2: Install Topgrade

Install Topgrade using Cargo:
```
sudo cargo install topgrade
```
Install additional necessary dependencies:
```
sudo cargo install cargo-update
```

Step 3: Run Topgrade

To update the entire system, execute:

topgrade

Note: It is recommended to run Topgrade with root privileges to ensure that all system components are updated correctly.

Step 4: Configure Automatic Updates

To automate updates every 60 minutes, create a systemd service and timer.

Create the Topgrade service:

sudo nano /etc/systemd/system/topgrade.service

Add the following content:

[Unit]
Description=Run Topgrade to update the system
After=network-online.target

[Service]
Type=oneshot
ExecStart=/root/.cargo/bin/topgrade -y

[Install]
WantedBy=multi-user.target

Create the timer:

sudo nano /etc/systemd/system/topgrade.timer

Add the following content:

[Unit]
Description=Timer to run Topgrade every 60 minutes

[Timer]
OnBootSec=10min
OnUnitActiveSec=60min
Persistent=true

[Install]
WantedBy=timers.target

Enable and start the timer:

sudo systemctl daemon-reload
sudo systemctl enable topgrade.service
sudo systemctl enable topgrade.timer
sudo systemctl start topgrade.timer

Security: Running Topgrade with root privileges is necessary to update all system components, but always review updates to avoid unwanted changes.

With Topgrade, keeping your system updated is easier than ever. Automate your updates and enjoy efficient software management!
