    Note: This is NOT the LTS (Long Term Support) release.
    Ubuntu 14.10 will be supported for 9 months for Ubuntu Desktop, Ubuntu Server, Ubuntu Core, Kubuntu, Ubuntu Kylin along with all other flavours.

    No need to upgrade from LTS to 14.10, but if you want to:
    Upgrading from Ubuntu 14.04 LTS
    To upgrade on a desktop system:
    • Press Alt+F2 and type in "update-manager" (without the quotes) into the command box.
    • Update Manager should open up and tell you: New distribution release '14.10' is available.
    • Click Upgrade and follow the on-screen instructions.
    To upgrade on a server system:
    • Install the update-manager-core package if it is not already installed.
    • Launch the upgrade tool with the command sudo do-release-upgrade.
    • Follow the on-screen instructions.

    Changes: No major changes (bug fixes, updated packages...)
    • Linux kernel 3.16 brings bug fixes and new hardware support, performance improvements in suspend/resume times, improved graphics performance on many Nvidia, Intel and ATI Radeon devices and also audio improvements with support for the Radeon .264 video encoder.
    • AppArmor improvements
    • Improved filesystem support (btfrs, XFS)
    • Unity has had many bugs fixed and features improved support for High-DPI displays.
    • Firefox is updated to version 33 and Chromium is updated to version 38.
    • LibreOffice 4.3
    • Gtk updated to version 3.12. Qt updated to version 5.3.
    • Support for IPP Everywhere printers is added, and printers shared from Ubuntu can emulate IPP Everywhere printers. IPP printers require no configuration under Ubuntu.
    • With Xorg 1.16, we have better support for non-pci devices. Xephyr now supports DRI3. The mesa 10.3 update has support for AMD Hawaii GPU's, improved support for dri3 offloading, the freedreno open source driver, and preliminary support for using nouveau on maxwell devices.
    • Other improvements for Ubuntu Server.

    Known issues
    Boot, installation and post-install
    • The amd64 (Intel x86 64bit) images specifically targeted at Apple hardware (amd64+mac) are no longer produced. Most Apple computers are now capable of booting the amd64 image directly using the EFI (not legacy) boot method
    • 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.
    • Machines with ATI/AMD video cards may be getting blank or entirely turned off screen at boot. The screen will switch on when the X server starts. If you need it to turn on prior to that, for example to unlock an encrypted harddisk hitting ESC twice should reset the video card to a working state.
    • An update to shim in 14.10 introduces a bug where, when booting on a UEFI system with SecureBoot disabled, the boot is delayed for two seconds and a message "Booting in insecure mode" is displayed on the screen. This message does not indicate a security problem with Ubuntu and does not interfere with the operation of the system except for introducing this boot delay. As a workaround to avoid this boot delay, users can enable SecureBoot if enabled on their hardware, or if they do not intend to use SecureBoot at all they can uninstall the shim-signed package and then rerun the grub-install command.
    Kernel
    • 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.)

    A small correction on the update process (depending on your O.S. settings additional steps were missing):
    Upgrading from Ubuntu 14.04 LTS
    To upgrade on a desktop system:
    • Open the "Software & Updates" Setting in Systemsettings.
    • Select the 3rd Tab called "Updates".
    • Set the "Notify me of a new Ubuntu version" dropdown menu to "For any new version".
    • Press Alt+F2 and type in "update-manager" (without the quotes) into the command box.
    • Update Manager should open up and tell you: New distribution release '14.10' is available.
    • Click Upgrade and follow the on-screen instructions.

    An alternative way is to launch update-manager from the command line with -d parameter:
    Code:
    sudo update-manager -d
