Ubuntu LTS release notes

Recommended system requirements:

• 2 GHz dual core processor or better
• 4 GB system memory
• 25 GB of free hard drive space
• Internet access is helpful
• Either a DVD drive or a USB port for the installer media

If you’re already running Ubuntu, you can upgrade in a few clicks from Software Updater.

If you’re using Windows 10 or any computer with a bit processor, we recommend the bit download.

Most Macs with Intel processors will work with either bit or Mac images. If the bit image doesn't work, try the Mac image.
