Ubuntu Pi image Ubuntu 20.04 LTS The version of Ubuntu with long term support, until April 2025.
Raspberry Pi Generic (64-bit ARM) preinstalled server image For modern Raspberry Pi boards (Pi 2, Pi 3 and Pi 4).
Which image should I pick? If you are wondering which download to pick, here are a few pointers on the options.
32 bit vs 64 bit The Raspberry Pi 2 only supports 32 bits, so that’s an easy choice. However the Raspberry Pi 3 and 4 are 64 bit boards. According to the Raspberry Pi foundation, there are limited benefits to using the 64 bit version for the Pi 3 due to the fact that it only supports 1GB of memory; however, with the Pi 4, the 64 bit version should be faster.
