First 2017 17.04 Alpha ISOs for Ubuntu and Lubuntu

Whilst the first of January maybe a public holiday for some it didn't stop Canonical releasing new Ubuntu and Lubuntu 17.04 (Zesty Zapus) Daily Build ISOs. So I've re-spun them to includes the 4.9 kernel with all the latest drivers and fixes for Bay Trail and Cherry Trail devices.

This is my first Lubuntu Alpha build ISO for anyone wanting to test the latest development work with the lightweight variant of Ubuntu.

Also as some Cherry Trail devices use the RTL8723BS wifi chip I've fine tuned these latest ISOs to improve its support.

To try an ISO download it from one of the links below (in red) and write it to a USB using either 'Rufus' in Windows or 'dd' in Linux.

Ubuntu (superseded)
Ubuntu comes with everything. All the essential applications, like an office suite, browsers, email and media apps come pre-installed and thousands more games and applications are available in the Ubuntu Software Centre.

Lubuntu (superseded)
Lubuntu is a fast, energy saving and lightweight variant of Ubuntu using LXDE. It is popular with PC and laptop users running on low-spec hardware.


  1. Hi I installed Lubuntu 17.04 Alpha on a Pendo pad 7"
    Install, boot and wifi works but not much else.
    Outline of issue:
    Touch Screen
    Battery is found but stuck at 100%
    No audio

    Name of device:
    Pendo 7"
    URL from pastebin:

    Also have a HWiNFO32 I'll post up to my git hub
    I will keep nutting away at it and try get every thing up and running.

    thanks mate

  2. Installed Lubintu on Vorke V1 (J3160).
    Works a lot faster, than 16.04

  3. Ian, Thanks for the first working Linux for Minix Neo Z64A. Much appreciated.

    I've been playing with the Lubuntu image (Lubuntu 17.04 Alpha0101 Linuxium). Will not report userland issues, because I've converted it to Mate, and that turned out a bit messy. Wifi performance is much improved vs your 16.04.1 LTS, no more huge CPU load.

    One issue which occurs both on the install itself as on the Live SD is, that the system will never reboot or shutdown. It will show the splash screen animation, and ask to remove the installation media (Live image), but will never actually reboot. I left it for an hour once, but still not.

    'shutdown -f now' also does not shutdown.



    1. The shutdown/reboot issue is a known issue still to be fixed unfortunately.

    2. Hi there
      Any news on this issue?

  4. Hiya, big thanks for the new iso's :)

    I installed the lubuntu one on my stick, started out great!
    But when i started some youtube videos or music from soundcloud, I get random audio pops.. Might it be some power saver settings intefering maybe? Any tips/ideas to how I might fix it?

    I randomly get half a second silence followed by a pop and sound comes back.

    Regards, stianfan

    1. Tried the ubuntu one, but it failed to install. got an dkpg error.

      and btw my stick is called BOXSTK1AW32SC


    2. I re-downloaded the ISO and tried it again with DD mode in rufus, got a second error now: Error installing grub-efi-amd64-signed.
      subprocess installed post-installation script returned error exit status 1

      Then i tried it again writing is ISO mode in rufus and got the same error.

      Seems like i got some corruption in my first DL, but still won't install for me.

      Then I DL'ed the "faster boot" one from your previous post, that one worked fine.

      Booting Try before option, or just install doesn't seem to make any difference.

      Hope this helps :-)

    3. oh, and also noticed that when i click past that error it tells me:"An error occured while instaling packages:
      E:Sub-process/usr/bin/dpkg returned an error code (1)

      The following packages are in a broken state:"

      But there is nothing listed.

    4. Most likely a package version has changed that I've missed or being an alpha build something has changed and is no longer compatible. In the interim, try installing without being connected to the internet (or vice-versa if your weren't connected) as this sometimes works as a workaround.

    5. Tried with and without internet, looks like the same error. It fails to install grub, but doing so manually doesn't get the install to boot either.

    6. Hey I was wondering if you found a solution? I am also getting this error when installing the ubuntu 17.04 iso. Weirdly the Lubuntu version of the ISO installs fine but has no sound and I get lots of broken dependencies when installing packages. The Ubuntu version has working sound and packages install fine when I used to live version but It wont install

    7. I did not unfortunately, so I'm sticking with 16.04 for now.

    8. I'm currently building new kernels and ISOs.

    9. Hi Ian,
      FYI, Got the exact same problem as Stian Fanavoll for Ubuntu, and Lubuntu is working fine. Have installed it on a Tablet, so i think ubuntu is better for the touch screen.


    10. Please try my latest Ubuntu pseudo Alpha 2 ISO as this is now fixed. This now supersedes the ISO above.

  5. Hi,

    I've tried to install both the Ubuntu and Lbuntu images on BayTrail Intel Stick, both internal storage and to a ssd connected on a usb hub. In both cases, it installs fine, the EFI Boot shows up in the bios, but it does not want to boot from it. If I attempt to force it (F10 in bios for boot menu) it tries to boot, and returns to the bios.

    Any ideas?

    Thank you kindly,

    1. Possibly the NVRAM is corrupt? Have you tried deleting all the boot entries using 'efibootmgr' and then recreating those you need?

      1. Start with the ICS switched off.
      2. Connect your LiveUSB (i.e. installation USB).
      3. Power on the ICS and press F10 and boot from the USB.
      4. Open a terminal windows and enter:
      sudo su -
      # if efibootmgr isn't already installed enter:
      apt-get install efibootmgr
      5. Remove any boot entries that may have been created through the earlier install or attempts to get things working by entering:
      for BOOTENTRY in 0 1 2 3 4 5 6 7 8 9
      efibootmgr -b ${BOOTENTRY} -B
      6. Create an Ubuntu boot entry by entering:
      efibootmgr -c -d /dev/mmcblk0 -p 1 -l \\EFI\\ubuntu\\grubx64.efi -L Ubuntu
      7. Reboot and press F10 and boot from the newly created Ubuntu entry.

      Note: This assumes you are booting from the 64-bit bootloader. If not you will need to modify the command in step 6 from 'grubx64.efi' to 'grubia32.efi'.

    2. Thanks a lot! I will give this a try :) (I assumed deleting the efi partition sorts this, and it is recreated by the installer).

    3. Deleting the EFI partition and adding new entries through the installer is often how the NVRAM gets corrupt as it seems to get out of sync. Using 'efibootmgr' is often the best/only way to fix it.

  6. FYI Android 7.1.1 x86_64 has been released with the 4.9 kernel, can you check it out and email them your patches since it sounds like they need em. :) https://groups.google.com/forum/#!topic/android-x86/MdaiRnECwtU

  7. Thank you for the above distro works brilliantly on my LINX 1010 finds all of the hardware including the sound. i have had problems with trying to install it to the i "hdd"(i now it isnt) but i think i need to clear out the UEFI of all old UBUNTU installs.

    many thanks

    1. Sometimes the NVRAM gets confused and a 'reset' is required to fix it.

  8. Tried lubuntu on "Morfine M1+" stick. Wifi, sound and video works. gnome-mplayer has problem playing video but mpv works fine.
    Overall better than Windows 10.

    1. Unfortunately Morefine the company isn't interested in running Ubuntu on their devices.

  9. Booted Lubuntu in live mode on Prestigio Smartbook 116A. Wifi works, but it seems me the sound works only after initial boot into Windows 10. The battery shows 100% all the time.

    1. Battery needs some additional patches which I am looking in to.

  10. Thanks for providing this.

    I've tried zesty-lubuntu-desktop-alpha-010117-linuxium.iso and get a blank screen. The blanks screen can be cleared by setting i915.modeset=0 on the linux line in the grub config.

    I have read that this kernel patch fixes the issue https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=bb98e72adaf9d19719aba35f802d4836f5d5176c. Is this patch in yout kernel?


    1. The patch is not in my released kernels but is in my development version which I am currently working on.

    2. Please try my latest Ubuntu pseudo Alpha 2 ISO to see if this is now fixed.

  11. Thanks for the efforts~!
    I have Acer Switch 10, I tried the 17.04 Alpha Ubuntu load 010117. it has a broadcom sdio wifi, with firmware not loading. dmesg | grep [i dont remember what I grepped for] gives:
    mmc0:0001:1: Direct firmware load for brcm/brcmfmac43241b4-sdio.bin failed with error -2.

    Is this enough info?

    Does this need a change built into the kernel, or is this something I can fix with a local mod outside of building a kernel?

    I found the file that was mentioned in the message in /lib/firmware/brcm/.


    1. Please try my latest Ubuntu pseudo Alpha 2 ISO to see if this is now fixed. If not, please make sure you have copied over the relevant NVRAM wifi text file from your Windows partition to see if this helps.

    2. Yes, I will try it.
      And if the NVRAM from windows needs to be tried, I will review and find how to do that.

    3. OK, pseudo alpha 2 is going, I got the same error, but this time I found a USB wifi laying around, so I uploaded the dmesg output. paste.ubuntu.com/23891051

      I'm not sure where to copy the text file from windows to... Is there a doc or a how-to?
      I did copy all the broadcom stuff I could find in windows/sys32/drivers

    4. I figured out what to do with the text file, and got the wifi working, , and I went to upload dmesg again and it took the session down. re-trying.

    5. After rebooting, and redoing to use only the built-in card, I can install "pastebinit", when I try to pipe the dmesg output into "pastebinit", the session crashes.

      Maybe the text file from windows for the NVRAM has some settings that don't work. I found the text file in windows from the listed drivers. I copied the file into a new file in /lib/firmware/brcm/ called brcmfmac43241b4-sdio.txt .

      I saved the dmesg output to a file, as well, I can try to "pastebinit" it, as well as the contents of the windows txt file.

    6. The dmesg output that would show the modpribe when I got the broadcom card working is: 23891666
      (I pasted the file I had saved earlier.)

      The contents of the text file from windows is in 23891671 .

    7. For the wifi issue did you copy across the Windows driver file stored in NVRAM? The file should look something like '/sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113' and you should copy it using 'cat /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 > /lib/firmware/brcm/brcm/brcmfmac43241b4-sdio.txt'. Substitute the NVRAM filename your find for the 'nvram-*' filename in the command.

      I've also released a version 2 of the pseudo Alpha 2 ISO so I'd be interested to hear how well that works on your device. The wifi still might not work until your copy across the Windows driver NVRAM file and also run 'sudo modprobe -r brcmfmac' followed by 'sudo modprobe brcmfmac' as before.

    8. OK, I'll try #3 version and try getting the NVRAM correctly, I was doing it wrong.
      I'll answer back to a newer blog entry.

  12. Tried on an ezbook 2 wifi work fine, boot speed is good but no sound, and battery indicator is not really optional for a netbook, funny fact when the battery is empty actually this machine just crash but don't turn off, need to force it to shutdown, thanks for your hard work. Amazing project. Love it.

    1. Please try my latest Ubuntu pseudo Alpha 2 ISO to see if this is now fixed. I've specifically added patches for the battery indicator.

  13. Tryed the live mode on Chuwi Hi10. 16.10 is booting nice. Did not try WIFI, sound or battery. 17.04 alpha tries to boot but does not reach to the desktop.

  14. Also it seems that booting Ubuntu 16.10 from the USB now prevents me to enter Android. Windows 10 boots OK but Android is stuck to CHUWI logo.

    1. I've respun my pseudo Ubuntu 17.04 pseudo Alpha 2 ISO as version 2. Please give it a try to see if it works better on your device.

  15. nice work!
    only one step away for daily usage.

    CSL Panther Tab 7 (Z3735G 1GB RAM)

    Wifi, Sound, Touch, Accelerometer, USB OTG

    not working:
    - auto rotate ( fixed with scripting https://gist.github.com/Links2004/5976ce97a14dabf773c3ff98d03c0f61 )
    - back light control ( screen LEDs always on )
    - without intel_idle.max_cstate=2 the system Freeze

    dmesg: https://gist.github.com/Links2004/93987ab3f0ae79423d1ccd548ce9320d

    the backlight problem is the only think blocking my from us it as main system, need to much battery if it stays on.

    have tried some kernel parameters for backlight but no they have no effect.

    not getting any useful controls in /sys/class/backlight/

    dmesg shows two think you may want to look for
    - a stack trace for mmc
    - [drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm chip

    1. Would you be willing to try a test kernel build to see if it addresses backlighting? I'd provide it as a kernel update script which means after testing you can simply purge the test kernel to return to the 'before testing' state.

    2. sure, with windows the tablet is useless anyway ;)

    3. I've updated my 'Bleeding edge Ubuntu 4.10.0-5.7 kernel with 17.04 pseudo Alpha 2 ISO' (see http://linuxiumcomau.blogspot.com.au/2017/01/bleeding-edge-ubuntu-4100-57-kernel.html) with a new ISO and kernel update script that should now help with the backlight issue. If you had previously installed my Version 3 release 2 ISO then you can simply download and install the Version 4 kernel upgrade script. If in any doubt it is better to download and use Version 4 ISO to ensure full support for the patched kernel.

    4. have tried the kernel update, and ISO booting no change.
      with out acpi_backlight=vendor i get a non functional
      /sys/class/backlight/acpi_video0 and with it noting.

      the logs still shows
      [drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm chip

      I can provide you more logs or dumps from the system if you need some.

    5. some good news i have found the GPIO's for the volume keys.

      GPIO 410 is volume down
      GPIO 411 is volume up

      gpiochip0: GPIOs 410-511, parent: platform/INT33FC:00, INT33FC:00:
      gpio-0 (sysfs ) in hi pad-85 offset:0xaa0 mux:0 up 20k
      gpio-1 (sysfs ) in hi pad-89 offset:0xb20 mux:0 up 20k

      currently I have no idea how I get linux to send them as keyboard input.

    6. @Links2004: Can you test backlight on https://goo.gl/BYADSn please?

    7. @Linuxium does not work, no change in the dmesg (Failed to own the pwm chip)

    8. Thanks. I'll have to think on this some more!
