Ubuntu 18.10 (Cosmic Cuttlefish) Beta released

The Ubuntu team is pleased to announce the final beta release of the
Ubuntu 18.10 Desktop, Server, and Cloud products.

Codenamed “Cosmic Cuttlefish”, 18.10 continues Ubuntu’s proud tradition
of integrating the latest and greatest open source technologies into a
high-quality, easy-to-use Linux distribution. The team has been hard
at work through this cycle, introducing new features and fixing bugs.

This beta release includes images from not only the Ubuntu Desktop,
Server, and Cloud products, but also the Kubuntu, Lubuntu, Ubuntu
Budgie, UbuntuKylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu flavours.

The beta images are known to be reasonably free of showstopper CD
build or installer bugs, while representing a very recent snapshot of
18.10 that should be representative of the features intended to ship
with the final release expected on October 18th, 2018.

Ubuntu, Ubuntu Server, Cloud Images:
Cosmic Final Beta includes updated versions of most of our core set
of packages, including a current 4.18 kernel, and much more.

http://releases.ubuntu.com/18.10/ (Ubuntu and Ubuntu Server on x86)

This Ubuntu Server image features the next generation Subiquity server
installer, bringing the comfortable live session and speedy install of the
Ubuntu Desktop to server users at last.

This new installer does not support the same set of installation options
as the previous server installer, so the “debian-installer” image
continues to be made available in parallel. For more information about
the installation options, please see:


Additional images can be found at the following links:

http://cdimage.ubuntu.com/netboot/18.10/ (Netboot)

As fixes will be included in new images between now and release, any
daily cloud image from today or later (i.e. a serial of 20180927 or
higher) should be considered a beta image. Bugs found should be filed
against the appropriate packages or, failing that, the cloud-images
project in Launchpad.
