# Defguard APT repository

### Distribution

Defguard APT repository provides packages for **Debian 12**, **Debian 13**, and **Ubuntu 22.04/24.04 LTS.**\
Packages are available on the default `trixie` repository distribution.

### Adding Defguard APT repository

To add Defguard APT repository, run following commands in your terminal:

```bash
sudo apt update 
sudo apt install -y ca-certificates curl 
#Add official Defguard public GPG key
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://apt.defguard.net/defguard.asc -o /etc/apt/keyrings/defguard.asc
sudo chmod a+r /etc/apt/keyrings/defguard.asc

#Add APT repository
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/defguard.asc] https://apt.defguard.net/ trixie release " | \
   sudo tee /etc/apt/sources.list.d/defguard.list > /dev/null 

sudo apt update
```

Afterward running these commands, you can install and update Defguard via APT.

After new release, simply use `sudo apt update` to update repository.

### Using pre-release builds

Defguard has two separate components on one APT repository, **release** and **pre-release.** If you want to install packages from pre-release, simply change `release` to `pre-release` in the installation steps described above, or run the following line.

```sh
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/defguard.asc] https://apt.defguard.net/ trixie pre-release " | \
   sudo tee /etc/apt/sources.list.d/defguard.list > /dev/null 
   
sudo apt update
```
