Can't boot the installer on Raspberry Pi 2

Hello,

I want to install Ubuntu Mate on my Raspberry Pi 2.

I have downloaded the image ubuntu-mate-15.04-desktop-armhf-raspberry-pi-2.img
I have transfered it to a SD card :

  • in Ubuntu and the ddrescue command
  • in Windows with Win32DiskImager

With both method the installer don’t boot : code lines scroll, then the screen goes black, then the same code lines scroll, then the screen goes black, etc …

What can I do?

EDIT : I have the same problem with this disk image : ubuntu-15.04-standard-raspberrypi2-armhf.img

Perhaps you microSDHC card is not compatible with the Pi 2?

Did you format the SD Card with SDFormatter in Windows? This should be done. Do you have a network cable plugged into your RaspPi2 while installing? I have done the install twice to my Rasp Pi2 of the same image and it has worked both times. I did notice a lot of network activity on the Pi during the install and having it connected to a router may be necessary.

If all else fails test the micro sd card by writing Rasbpian to it and then installing that just to make sure the problem is not the card - then format the card again and try the Ubuntu Mate install.

Hello,

I was trying to install with the Pi connected to a touch screen.
It works now with another display.

But I have another problem :
the resolution is 1824x984 and I can’t change it
the desktop does not fit the screen and the refresh rate is indicated as 0Hz

What can I do?

EDIT : There is an error message while booting :
“Failed to start load kernel modules”

@favancini1108 To disable overscan, edit the file /boot/firmware/config.txt and uncomment disable_overscan=1 (line number 10). The changes should be applied on reboot :smiley:

I had that same error message when booting. I asked here and apparently it is common and has not effected running the OS.

I am having a similar problem. I formatted the SD card and then used Win32DiskImager to write the image. I have tested the SD card multiple times with Rasbpian and it runs (format and diskimage)

I am getting the rainbow screen and the green light flashes 7 times which I understand the kernel image cannot be found. I tried updating the config.txt with the boot_delay=1
but I am getting the same error. I can see a kernel7.img in the root

Hello, I have the same problem as you … can you resolve it? How?
Thank you Mirek

I’m not even sure how to get Ubuntu on my Raspberry Pi…

I downloaded the img.xz file onto my laptop then transferred it to my SD Card but then nothing is happening what so ever…
Am I doing something wrong??

You don’t say how exactly you ‘wrote’ the file to SD card.
This is a compressed format, which is useles if written ‘as is’ to the card.
The ubuntu-mate release stuff talks about how to get this onto the card.
