How to run Ubuntu on PS4 with FW1.76 -

Last week the last piece came together to run the Linux loader on the PS4 with 1.76FW, now it wasn’t what you saw failoverflow run but it was a big step in the right direction. Soon or later someone was going to get a full Linux distro working on the PS4 and today that’s what happen, as seen in this YouTube video below.

Here’s a little guide from playstationhax.it member fx0day on how you to can get this working on your PS4.

What you need:

PS4 with Fw 1.76
Ubuntu
USB HDD or a USB thumb drive big enough to install Ubuntu.

1 Download the Iso

2 Copy the iso to Usb with a tool like unetbootin (Win/mac/linux) https://unetbootin.github.io/ (You can burn on a Dvd also)

3 Boot on this Usb or Dvd

4 Launch Install on your Usb HDD or Usb key (you can make small partition in Fat32 for Bzimage and initramfs) and the rest in Ext4

I’ve used the ubuntu-14.04.4-desktop-amd64.iso and made the install on my USB HDD (with a PC of course) , nothing more to say here just configure your keyboard layout , password …)

So now you should have Ubuntu installed on your USB HDD …

Now go to the PS4-Playground and load Linux (you must have of course a USB key with bZimage & initramfs.cpio.gz in the PS4)

Now you should see better-initramfs shell …

Plug the Usb Hdd where you have your ubuntu install (At this point you can remove the Usb key with bZimage & initramfs.cpio.gz everything is in RAM)
Type fdisk -l to see the name of your Usb Hdd ( /dev/sdXX)

As you can see my ubuntu partition is in /dev/sdc1
Now just type (if your bootable partition is sdc1)

mount /dev/sdc1 newroot/
exec switch_root /newroot/ /newroot/sbin/init

Sometimes exec switch_root don’t start at the first time , just type the command again ..

Wait a few seconds and you should see Ubuntu running

Keep in mind that there’s no network working yet
