Alongside enough storage to hold the Ubuntu Core image, installation on a Raspberry Pi also requires a screen and keyboard to navigate a few installation prompts. These aren’t needed post-installation.
Additionally, you will need an Ubuntu SSO account, with associated SSH keys. This setup is required because, after Ubuntu Core has been installed, Ubuntu SSO is used to login to your device. For help importing SSH keys, see the Ubuntu community wiki.
When Ubuntu Core is up and running, if you want to access your device remotely, you’ll need an SSH client for your operating system. Linux and macOS both have clients built-in, whereas Windows users could use Ubuntu on WSL.
