To run Ubuntu on Android/Samsung you need to create an img file using my post, you can also use two of my start and stop scripts from here start stop.
Lets begin by preparing our device by create an folder on android, connect your phone to your computer and do:
1 sudo adb shell 2 cd /sdcard 3 mkdir ubuntu 4 exit
Now you can upload the img file and if you like you can also upload my start and stop scripts.
1 sudo adb push ubuntu.img /sdcard/ubuntu 2 sudo adb push startA_ubuntu.sh /sdcard/ubuntu 3 sudo adb push stopA_ubuntu.sh /sdcard/ubuntu
Now that you have done all the prep work you can use your ubuntu by doing:
1 su 2 cd /sdcard/ubuntu 3 sh startA_ubuntu.sh ubuntu.img Step 4:
1 exit 2 sh stopA_ubuntu.sh
