Dubbed as the ???Disco Dingo,??? Ubuntu 19.04 was released on April 18th, 2019, and it was supported for 9 months. Ubuntu 19.04 was the first Ubuntu release to adopt the Linux 5.0 kernel series. This added quite some goodies, including AMD FreeSync display support, advanced ARM hardware support, Btrfs swap files, support for Raspberry Pi touchscreens, and support for the Adiantum file system encryption. But, as all good things must come to an end, starting January 23rd, 2020, Ubuntu 19.04 (Disco Dingo) is no longer a supported release. Canonical will stop seeding software updates and security patches. Therefore, if you’re still using Ubuntu 19.04, you will have to upgrade to the latest release, Ubuntu 19.10 (Eoan Ermine), as soon as possible.
