The RootFS Auto-resize feature has changed!!!

And press the power button or unplug-plug the DC plug when the blue LED is off.

• Tons of issues undocumented.
• 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.

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo reboot

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.

target

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.

target

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

If everything goes well, you will see this message.
