Today, I received the email, regarding the life of Ubuntu 17.10. You will see it is end of life on July 19, 2018, means Today.
If you are still using Ubuntu 17.10, you would better to upgrade to Ubuntu 18.04.
This is a follow-up to the End of Life warning sent earlier this month
to confirm that as of today (July 19, 2018), Ubuntu 17.10 is no longer
supported. No more package updates will be accepted to 17.10, 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 17.10 (Artful Aardvark) release almost 9 months
ago, on October 19, 2017. As a non-LTS release, 17.10 has a 9-month
support cycle and, as such, the support period is now nearing its
end and Ubuntu 17.10 will reach end of life on Thursday, July 19th.
At that time, Ubuntu Security Notices will no longer include
information or updated packages for Ubuntu 17.10.
The supported upgrade path from Ubuntu 17.10 is via Ubuntu 18.04.
Instructions and caveats for the upgrade may be found at:
Ubuntu 18.04 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:
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.
