The links below are for the current 17.04 release. It’s better to use the (magnet) link first (auto-verified downloads). Take time to read the Release Notes (being updated). For low-RAM (less than 700 MB) PCs use the Alternate versions (installer screenshots and instructions).
About the architecture:
- 32-bit version, suitable for almost all PCs. Choose this if unsure.
- 64-bit version for Intel or AMD computers. You may need a 32-bit ISO, for PCs older than 2007.
- PowerPC version for Apple Macintosh G3/G4/G5 and IBM OpenPower. LTS only.
- Mac64 version for Intel Macs, 2006 and beyond. After 14.04, use 64-bit version.
Raspberry Pi 2 & 3 (16.04)
This image was created using the Ubuntu Pi Flavour Maker. We have done what we can to optimise the builds for the Raspberry Pi 2 but microSDHC I/O throughput is a bottleneck so we recommend that you use a Class 6 or Class 10 microSDHC card. More information here.

Version 14.04.5 LTS
