Ubuntu Linux 19.04 (Disco Dingo) will reach it's end of life on Thursday, Jan 23rd.

Ubuntu announced its 19.04 (Disco Dingo) release almost 9 months ago, on April 18, 2019. As a non-LTS release, 19.04 has a 9-month support cycle and, as such, the support period is now nearing its end and Ubuntu 19.04 will reach end of life on Thursday, Jan 23rd.
At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 19.04.

The supported upgrade path from Ubuntu 19.04 is via Ubuntu 19.10. Instructions and caveats for the upgrade may be found at:

Ubuntu 19.10 continues to be actively supported with security updates and select high-impact bug fixes. Announcements of security updates for Ubuntu releases are sent to the ubuntu-security-announce mailing list, information about which may be found at:

Since its launch in October 2004 Ubuntu has become one of the most highly regarded Linux distributions with millions of users in homes, schools, businesses and governments around the world. Ubuntu is Open Source software, costs nothing to download, and users are free to customise or alter their software in order to meet their needs.
