Ubuntu 19.04 (Disco Dingo) the first daily build image open download
with the official launch of the Ubuntu 19.04 system by Canonical earlier this week, daily build ISO images for early adopters are also available for download today. The official version of Ubuntu 19.04 (Disco Dingo) is expected to be released on April 18, 2019, with a nine-month support cycle that continues until July 2020. Its development cycle began on October 25, 2018, and daily build images are available for download.
Of course, the daily build image released today is still based on Ubuntu 18.10 (Cosmic Cuttlefish) released last month, so don't expect any new features or enhancements, which will not be too different from the Ubuntu 18.10 live image.
users who are currently interested can go to Canonical's server to download the first daily build ISO image of Ubuntu 19.04 (Disco Dingo), but only 64-bit versions are supported and no other flavors versions are available.
