 登录到已经部署的 Open Media Vault 使用如下命令可以替换 Open Media Vault 镜像源。
 
+```bash
+omv-env set OMV_APT_REPOSITORY_URL "https://{{ site.hostname }}/OpenMediaVault/public"
+omv-env set OMV_APT_ALT_REPOSITORY_URL "https://{{ site.hostname }}/OpenMediaVault/packages"
+omv-env set OMV_APT_KERNEL_BACKPORTS_REPOSITORY_URL "https://{{ site.hostname }}/debian"
+omv-env set OMV_APT_SECURITY_REPOSITORY_URL "https://{{ site.hostname }}/debian-security"
+# 如果你有安装 omv-extras 则需要运行如下命令更改源

+1. 由于 Open Media Vault 自带 kernel backports 因此在 `/etc/apt/source.list` 中配置 backports 源会造成冲突。
+2. 由于 Open Media Vault 的公钥分发通过源自己携带完成，因此本身存在被篡改的可能性，故在换源后用户需要通过其他渠道验证获取的公钥的正确性。

+### 首次部署 Open Media Vault
+
+对于首次部署操作步骤以 <https://openmediavault.readthedocs.io/en/latest/installation/on_debian.html> 为准
+
+我们仅对 **Add the package repositories** 段落做出如下调整
+
 ```bash
 cat <<EOF > /etc/apt/sources.list.d/openmediavault.list
 deb https://{{ site.hostname }}/OpenMediaVault/public usul main
+deb https://{{ site.hostname }}/OpenMediaVault/packages usul main
