This is a follow-up to the End of Life warning sent earlier this month to confirm that as of today (July 18, 2019), Ubuntu 18.10 is no longer supported. No more package updates will be accepted to 18.10, and it will be archived to old-releases.ubuntu.com in the coming weeks.
The original End of Life warning follows, with upgrade instructions:
Ubuntu announced its 18.10 (Cosmic Cuttlefish) release almost 9 months ago, on October 18, 2018. As a non-LTS release, 18.10 has a 9-month support cycle and, as such, the support period is now nearing its end and Ubuntu 18.10 will reach end of life on Thursday, July 18th.
At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 18.10.
The supported upgrade path from Ubuntu 18.10 is via Ubuntu 19.04. Instructions and caveats for the upgrade may be found at:
https://help.ubuntu.com/community/DiscoUpgrades
Ubuntu 19.04 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:
https://lists.ubuntu.com/mailman/listinfo/ubuntu-security-announce
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.
