Before we start the installation of Ubuntu Server to Synology NAS, you will need to download the Ubuntu Server ISO image from Ubuntu.com. As of the time of writing, the version of Ubuntu Server stands at 20.10, and the file size is almost 1GB.
Once the download started, you can log in to your Synology NAS’s DiskStation Manager (DSM) to install the Virtual Machine Manager from Package Center.
What I gathered after reading the official site in the link above is that you can install or rather dual boot Ubuntu into Android 2.3 (Gingerbread) and above.
