Release Note of Ubuntu Minimal 18.04 LTS (v1.0)


Release Date 2018-05-31
Release Type release

File name : ubuntu-18.04-4.14-minimal-odroid-xu4-20180531.img.xz

If you need a Desktop GUI, you have to download MATE image instead of this minimal image.

XU4 OS image is fully compatible with HC1, HC2, MC1 and XU3.

  • Linux Kernel LTS 4.14.43
  • U-Boot 2017.05
  • Mali GPU driver for framebuffer(fbdev) can be installed with “apt install mali-fbdev”
  • Kodi 17.6 package for fbdev can be installed with “apt install kodi-fbdev”.
The RootFS Auto-resize feature has changed!!! 
Once everything is done after auto-resize, the power will turn off automatically. Wait a couple of minutes.
And press the power button or unplug-plug the DC plug when the blue LED is off.
  • Tons of issues undocumented. :-x
  • Kodi supports only H.264 video format at this moment. MPEG4/MPEG2 video decoding is very unstable.
  • To change CPU governor to “ondemand”, refer this guide
    boot.ini tweaking doesn't work with Kernel 4.14 any more.
  • Some UASP capable USB-to-SATA bridge controllers are not compatible. If your external HDD is not working properly, add its VID/PID in boot.ini Boot arguments to disable the UAS function something like this.
  • usb-storage.quirks=0x0bc2:0x2322:u

We freshly flashed “ubuntu-16.04.3-4.14-minimal-odroid-xu4-20171213.img.xz” OS image to a SD card and followed below steps.
Answer “Yes” to all the questions.
But you have to choose “No” menu when you meet a dialog box of “Do you want to abort removal now?” in the last step.

sed -i "s/xenial/bionic/g" /etc/apt/sources.list
sed -i "s/xenial/bionic/g" /etc/apt/sources.list.d/odroid.list
rm /etc/apt/sources.list.d/saiarcot895-ubuntu-myppa-xenial.list
apt-get update
apt-fast dist-upgrade
apt-get remove linux-image-xu3
apt-get remove linux-image-4.14*

And finalize the upgrade process.

apt-get install linux-odroid-5422
apt-get autoremove
reboot

If everything goes well, you will see this message.
