Updated Packages
As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian´s unstable branch; others have been explicitly pulled in for Ubuntu 14.10.

For a list of all packages being accepted for Ubuntu 14.10, please subscribe to utopic-changes.

Linux kernel 3.16

The Ubuntu 14.10 release delivers a v3.16 based kernel. This brings a significant number of bug fixes and new hardware support including expanded architecture support for Power 8 and arm64 platforms. It also includes support for Intel Cherryview, Haswell, Broadwell and Merrifield systems, and initial support for Nvidia GK20A and GK110B GPU’s. There is improved graphics performance on many Nvidia, Intel and ATI Radeon devices and also audio improvements with support for the Radeon .264 video encoder. Expanded platform support is enabled via support for 64 bit EFI boot on 32 bit EFI BIOS. This release also brings performance improvements in suspend/resume times.

For developers we see significant improvements in tracing and debugging with new triggers for kernel trace points, and expansion of uprobe support. This release also brings a new experimental deadline CPU scheduler.

For servers we see better support for bursty workloads, improved resident set tracking, and a better NUMA migration strategy. Filesystem support is also improved with faster file allocations for database use and several filesystems show performance improvements including XFS and Btrfs. XFS now has stabilized its v5 format and sports expanded direct I/O support. Btrfs now supports per directory switchable compression modes. raid5 performance is also improved. This release also brings improvements to networking, including a new packet scheduler for high latency links, and efforts to bring IPv6 support in line with IPv4. We see performance improvements for openvswitch and VTI tunneling. As always, various new pieces of hardware are now supported including Intel AVX-512 and Intel MXP.

On cloud we see Hyper-V, XEN, and KVM networking performance improvements. Hyper-V now supports the hypervisor driven file copy and reference time services. For KVM we see improved support for passing through new x86 vector instructions.

On the security front we see full Kernel Address Space Layout Randomisation applied to the kernel and its modules, plus the closure of a number of information leaks in /proc. We also see additional support for cryptographic devices.


AppArmor added support for fine-grained mediation of unix(7) abstract and anonymous sockets and also added various policy updates and bug fixes. AppArmor policy has been adjusted for packages that ship it to work with these changes, but local policy may need to be adjusted unix rules. See man 5 apparmor.d for details.


Oxide has been updated to use the latest Chromium Content API and includes numerous bug fixes and features to better support webbrowser-app, webapps and apps using UbuntuWebViews. Oxide is a webview based on Chromium to deliver web content. Oxide allows us to better support 3rd party developers and applications within the Ubuntu archive by providing a fast, secure and up to date webengine library for the duration of this release. While other web content libraries such as those based on webkit are available, their maintenance will be limited to new upstream minor version releases only, and application developers are encouraged to use Oxide instead.

Ubuntu 14.10 includes the OpenStack 2014.2 (Juno) release of the following projects in Ubuntu main:

OpenStack Compute - Nova
OpenStack Identity - Keystone
OpenStack Imaging - Glance
OpenStack Block Storage - Cinder
OpenStack Networking - Neutron
OpenStack Object Storage - Swift
OpenStack Telemetry - Ceilometer
OpenStack Orchestration - Heat
OpenStack Dashboard - Horizon
WARNING: Upgrading an OpenStack deployment is a non-trivial process and care should be taken to plan and test upgrade procedures which will be specific to each OpenStack deployment.

Libvirt 1.2.8

Containers launched with libvirt-lxc can now be apparmor-protected.

Cgmanager support allows libvirt to be used in containers without cgroups mounted.

LXC 1.1

This includes container checkpoint and restart as a tech preview.

Known issues
As is to be expected, at this stage of the release process, there are some significant known bugs that users may run into with this release of Ubuntu 14.10. The ones we know about at this point (and some of the workarounds), are documented here so you don´t need to spend time reporting these bugs again:

Boot, installation and post-install
Due to changes in syslinux, it is not currently possible to use usb-creator from 14.04 and earlier releases to write USB images for 14.10; we believe that it is also not possible to use usb-creator from a 14.10 system to write USB images for earlier releases. For now the workaround is to use a matching release of Ubuntu to write the images, but we intend to issue updates soon to work around this incompatibility. 1325801
Power Management
Under certain circumstances (so far only reproducible in certain VM environments), lightdm will fail to start on boot. It can be manually started from a console with "sudo service lightdm start". This will be resolved shortly after beta-2 is out.

Graphics and Display
When booting virtual machines installed with encrypted root and using "VGA" as the video adapter it may not be possible to enter the unlock password. Switching Video to QXL will allow booting of these instance. (See 1383851 for details.)

For a listing of more known issues, please refer to the Utopic Unicorn bug tracker in Launchpad.
