更新程式庫清單並開始安裝 OMV 並跑一次更新
apt-get update
apt-get --yes --auto-remove --show-upgraded \
--allow-downgrades --allow-change-held-packages \
--no-install-recommends \
--option DPkg::Options::="--force-confdef" \
--option DPkg::Options::="--force-confold" \
install openmediavault-keyring openmediavault
#更新
omv-confdbadm populate
#顯示登入資訊
cat /etc/issue
按照顯示的登入資訊開啟瀏覽器連上，就可以開始使用 Openmediavault 管理儲存空間了。
如果要安裝 omv-extras 提供額外的附加程式與 docker 的話，可以順道一併安裝：
wget -O - https://github.com/OpenMediaVault-Plugin-Developers/packages/raw/master/install | bash
之後進 OMV 管理台安裝 docker 與附加程式即可。
