此教程参考于Abin17618的R3300L安装armbian（bullseye 23.08.0）并装OMV，已发私信给Abin17618，如有侵犯会立即删除。
1、首先安装好armbian系统，然后更换更换国内源：
我使用的是LinuxMirrors的一键更换执行命令https://supermanito.github.io/LinuxMirrors/use/
执行此命令：
bash <(curl -sSL https://linuxmirrors.cn/main.sh)
2、更新软件：
执行此命令：
apt update && apt upgrade -y
3、手动安装 openmediavault 密钥环：
执行以下命令：

apt-get install --yes gnupg
wget -O "/etc/apt/trusted.gpg.d/openmediavault-archive-keyring.asc" https://packages.openmediavault.org/public/archive.key
apt-key add "/etc/apt/trusted.gpg.d/openmediavault-archive-keyring.asc"
4、添加清华源软件包储存库加速
部分参考了https://mirrors.tuna.tsinghua.edu.cn/help/openmediavault/
执行以下命令：

cat <<EOF > /etc/apt/sources.list.d/openmediavault.list
deb https://mirrors.tuna.tsinghua.edu.cn/OpenMediaVault/public shaitan main
deb https://mirrors.tuna.tsinghua.edu.cn/OpenMediaVault/packages shaitan main
## Uncomment the following line to add software from the proposed repository.
# deb https://mirrors.tuna.tsinghua.edu.cn/OpenMediaVault/public shaitan-proposed main
# deb https://mirrors.tuna.tsinghua.edu.cn/OpenMediaVault/packages shaitan-proposed main
## This software is not part of OpenMediaVault, but is offered by third-party
## developers as a service to OpenMediaVault users.
# deb https://mirrors.tuna.tsinghua.edu.cn/OpenMediaVault/public shaitan partner
# deb https://mirrors.tuna.tsinghua.edu.cn/OpenMediaVault/packages shaitan partner
EOF
5、启动科学环境或者使用Windows启动clash，使用clash的http代理端口
可文件里面最下面添加下面三条命令：（其中192.168.2.240更换为Windows的IP）

nano /etc/profile
export http_proxy="http://192.168.2.240:7890"
export https_proxy="http://192.168.2.240:7890"
export ftp_proxy=$http_proxy
6、OMV自动安装的脚本，装完后包含omv-extras插件：
执行以下命令：
wget -O - github.com/OpenMediaVault-Plugin-Developers/installScript/raw/master/install | sudo bash
可能要等不少于半小时吧，根据视网络情况而定。搞定后会自动重启。
看到这条就说明安装完毕了等重启即可
IP address may change and you could lose connection if running this script via ssh  
PS：安装到最后可能会更换IP，这个时候进路由器看一下新的IP地址即可。
