Final Beta of Ubuntu 16.04 LTS Available for Download

Last updated: March 25, 2016

The final beta of Ubuntu 16.04 LTS, codenamed “Xenial Xerus”, has been released today!

The beta release features images for not only the Ubuntu Desktop, Server, Cloud, and Core products, but also the Kubuntu, Lubuntu, Mythbuntu, Ubuntu GNOME, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu flavours.

New Features in Ubuntu 16.04 LTS:

  • based on Linux Kernel 4.4
  • python has been upgraded to the 3.5 series
  • golang toolchain was upgraded to the 1.6 series, and gcc-go was upgraded to the GCC6 branch.
  • includes a new port to 64-bit z/Architecture for IBM mainframe computers.
  • GNOME is mostly upgraded to 3.18. GLib upgraded to to 2.48 (corresponding to GNOME 3.20)
  • Ubuntu Software Center is replaced by Gnome Software.
  • Improved HiDPI support
  • Unity online searches disabled by default.
  • Unity Launcher can be moved to bottom

There is, however, one bug in this beta serious, and will be fixed before release:

In some cases, attempts to install to a hard drive that already contains a swap partition may fail in the partitioning phase. If you encounter this, the simplest workaround is to boot to the live session, start a terminal (Ctrl-Alt-T) and type “sudo swapoff -a”. You can then start the installation from the icon on the desktop and it should proceed successfully.

    How to Install / Upgrade to Linux Kernel 4.5 in Ubuntu

    Last updated: March 15, 2016

    The Linux Kernel has reached the new stable 4.5 release. Linus Torvalds yesterday announced:

      So this is later on a Sunday than my usual schedule, because I just couldn’t make up my mind whether I should do another rc8 or not, and kept just waffling about it. In the end, I obviously decided not to,
      but it could have gone either way.

      We did have one nasty regression that got fixed yesterday, and the networking pull early in the week was larger than I would have wished for. But the block layer should be all good now, and David went through all his networking commits an extra time just to make me feel comfy about it, so in the end I didn’t see any point to making the release cycle any longer than usual.

      And on the whole, everything here is pretty small. The diffstat looks a bit larger for an xfs fix, because that fix has three cleanup refactoring patches that precedes it. And there’s a access type
      pattern fix in the sound layer that generated lots of noise, but is all very simple in the end.

      …

    Download and Install Linux Kernel 4.5:

    NOT recommended for “normal” users! You MUST know what you’re going to do and how to revert the changes.

    Ubuntu Kernel Team has made the binary packages for this kernel release, available for download at the link below:

    Download Kernel 4.5 (DEBs)

    First check out your OS type, 32-bit, 64-bit, then select install below packages one by one:

    1. linux-headers-4.5.0-xxx_all.deb
    2. linux-headers-4.5.0-xxx-generic_xxx_i386/amd64.deb
    3. linux-image-4.5.0-xxx-generic_xxx_i386/amd64.deb

    If you need a low latency system (e.g. for recording audio) then download & install below packages instead:

    1. linux-headers-4.5.0-xxx_all.deb
    2. linux-headers-4.5.0-xxx-lowlatency_xxx_i386/amd64.deb
    3. linux-image-4.5.0-xxx-lowlatency_xxx_i386/amd64.deb

    For command line, download and install the kernel debs via:

    For 64-bit system:

    cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/linux-headers-4.5.0-040500_4.5.0-040500.201603140130_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/linux-headers-4.5.0-040500-generic_4.5.0-040500.201603140130_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/linux-headers-4.5.0-040500-generic_4.5.0-040500.201603140130_i386.deb

    Spotify Client 1.x Goes Stable, How to Install it in Ubuntu

    Last updated: March 10, 2016

    Linux Spotify client 1.x finally goes stable! The stable Linux repository added support for Ubuntu 16.04 LTS, and Ubuntu 15.10.

    Due to lack of developers working on the Linux client, Spotify 1.x takes 9 months of development to be made into stable repository,

    In June 2015 we released version 1.x of the client for Linux in the testing repository.

    The intention was to fix a few of the bigger issues and then quickly move this to stable. That never happened, since after September, we have had no developers working on the linux client. There are still lots of problem with this version of the client for linux, but we are now seeing much more problems with the old client.

    …

    Read the community announcement for more details.

    How to Install Spotify Client 1.x in Ubuntu:

    The client now is available for all current Ubuntu releases. Ubuntu 16.04 and Ubuntu 15.10 does not longer need to manually install the libgcrypt11 library.

    If you’ve the testing repository added in your system, disable/remove it first via Software & Updates -> Other Software tab.

    1. Launch terminal from App Launcher, or via Ctrl+Alt+T shortcut key. When it opens, paste below command and run to add the stable Spotify repository for Linux:

    echo deb http://repository.spotify.com stable non-free | sudo tee /etc/apt/sources.list.d/spotify.list

    Type in your password (no visual feedback when typing) when it asks and hit Enter.

    2. Add the key so that your Ubuntu will trust the packages from that repository:

    sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys BBEBDCB318AD50EC6865090613B00F1FD2C19886

    3. Finally install the client via Synaptic Package Manager (after clicked Refresh button), or by running below commands in terminal one by one:

    sudo apt-get update

sudo apt-get install spotify-client
