Support for Ubuntu Linux 17.04 will be discontinued on January 13, 2018

Ubuntu announced its 17.04 (Zesty Zapus) release almost 9 months ago, on
April 13, 2017. As a non-LTS release, 17.04 has a 9-month support cycle
and, as such, will reach end of life on Saturday, January 13th.

At that time, Ubuntu Security Notices will no longer include information or
updated packages for Ubuntu 17.04.

The supported upgrade path from Ubuntu 17.04 is via Ubuntu 17.10.
Instructions and caveats for the upgrade may be found at:

https://help.ubuntu.com/community/Upgrades

Ubuntu 17.10 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:

https://lists.ubuntu.com/mailman/listinfo/ubuntu-security-announce

Development of a complete response to the highly-publicized Meltdown and
Spectre vulnerabilities is ongoing, and due to the timing with respect to
this End of Life, we will not be providing updated Linux kernel packages for
Ubuntu 17.04. We advise users to upgrade to Ubuntu 17.10 and install the
updated kernel packages for that release when they become available.

Spectre vulnerabilities, see:

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.
