# 添加 Better-Deepin-REPO / Deepin_25 APT 源

APT 源地址：

```text
https://obsci.odata.cc/Better-Deepin-REPO/Deepin_25/
```

> 说明：这是 OBS 生成的 flat repository，源行最后使用 `/`，不要写 `stable main`、`bookworm main` 这类发行版组件。

## 1. 安装必要工具

```bash
sudo apt update
sudo apt install -y ca-certificates curl gnupg
```

## 2. 添加仓库 GPG 密钥

```bash
sudo install -d -m 0755 /etc/apt/keyrings

curl -fsSL https://obsci.odata.cc/Better-Deepin-REPO/Deepin_25/Release.key | \
sudo gpg --dearmor -o /etc/apt/keyrings/better-deepin-repo.gpg
```

## 3. 添加 APT 源

```bash
echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/better-deepin-repo.gpg] https://obsci.odata.cc/Better-Deepin-REPO/Deepin_25/ /" | \
sudo tee /etc/apt/sources.list.d/better-deepin-repo.list
```

## 4. 更新软件包索引

```bash
sudo apt update
```

## 5. 查看源是否添加成功

```bash
apt-cache policy
```

或者查看某个包：

```bash
apt policy
```

例如：

```bash
apt policy waydroid
```

## 6. 安装软件包

```bash
sudo apt install
```

例如：

```bash
sudo apt install waydroid
```

## 7. 删除该 APT 源

```bash
sudo rm -f /etc/apt/sources.list.d/better-deepin-repo.list
sudo rm -f /etc/apt/keyrings/better-deepin-repo.gpg
sudo apt update
```

## 可选：添加源码包源

如果需要 `apt source`，可以额外添加 `deb-src`：

```bash
echo "deb-src [signed-by=/etc/apt/keyrings/better-deepin-repo.gpg] https://obsci.odata.cc/Better-Deepin-REPO/Deepin_25/ /" | \
sudo tee -a /etc/apt/sources.list.d/better-deepin-repo.list
```
