Installation fails on Mac OSX 10.10.4 using qt_host_installer.app

ProperJob · 27 July 2015 08:20

I formatted the SD Card using the SDFormatter from https://www.sdcard.org/ with the Logical Address Adjustment set to ‘yes’. (Actually I’ve tried LAA set to yes and no).

I’ve tried to install 2015.6-1 (is that the 1.0 release?) for Raspberry Pi 2 on 2 different Macs using qt_host_installer.app.
I dragged the qt_host_installer.app into the /Applications folder and ran it from there.
Every time it fails with the error message below:

Could not mount device XYZ. Check the log for error messages. OSMC must exit now.

The log is as follows

What do you see on the disk if you insert it ?

From the log it appears the image was written correctly (the dd if=/Users…) but it was unable to remount the fat partition to write the preseed.cfg file.

This may not be an issue for you unless you have pre-configured Wifi or Network settings (this is what preseed.cfg is for) but it would be nice to get to the bottom of this issue.

Are you logged in as an administrative user ?

After re-inserting the disk can you run the following command from a terminal and post the output ?

diskutil list

ProperJob · 27 July 2015 11:48

I can’t actually mount the sd card (see screenshot). Maybe that’s the problem.

I’m going to try and re-format using disk utility and try the installation again.

ProperJob · 27 July 2015 12:40

I think there is a problem with the sd card or the sd card reader that I’m using.

DBMandrake · 27 July 2015 13:26

Yep does seem likely. Try another SD card and/or card reader and see if that works.

What size and model of card is it by the way ?

ProperJob · 27 July 2015 13:45

It’s a Kingston SD10V/16GB

ProperJob · 28 July 2015 17:55

That was definitely an SD card issue. I got a new card and all the problems went away. Thank you for your help.

Hi!

I stumbled upon this thread, because I had the exact same problem: failing installer, ‘unreadable disk’-message, missing space on a formatted card. So I also suspected a faulty SD card. However, that wasn’t the case…

I tried 3 different SD cards:

some 8GB Micro SD hc class 4
SanDisk 32GB micro SD ULTRA Class 10 UHS-I (hardly used)
Samsung 32GB micro SD EVO+ Class 10 UHS-I (brand new)

With 2 different ‘setups’:

with SD-card adapter, directly in my Mac’s SD-slot
with SD-card reader, connected via USB

Neither of the 6 combinations worked, each setup resulted in the ‘could not mount’ error message in the installer.

But… I managed to setup OSMC (for RPi 2b) by doing a manual installation.

I couldn’t find a compact and complete howto, so I’ll share the steps and info here.

manual installation

format the SD with ‘SD Card Formatter’: SD Memory Card Formatter for Windows/Mac | SD Association
option: ‘Overwrite format’
file system should be FAT32 after formatting (it looks like the formatter-tool does that by default)

If it’s not FAT32, you can format your SD commandline (didn’t need to do this myself):

diskutil list

find the location, e.g. /dev/disk2

sudo diskutil eraseDisk FAT32 MYSDCARD MBRFormat /dev/disk2

now download the disk-image on Download - OSMC
be sure to pick the correct one! (in my case the Raspberry Pi 2 / 3 version, otherwise your Pi will be stuck on the rainbow-bootscreen. Trust me, I know )
I used Etcher https://etcher.io/ to burn the image to the SD card
Plug in the SD-card in your Pi and complete the setup!

I hope this info can be helpful to other users with the same issue.

By the way, I used the installer about a year ago on the 8GB card and it worked like a charm then. So it looks to me like it’s a problem with this version of the installer.

sam_nazarko · 7 July 2017 15:10

We’re looking in to it. For now, you can just manually flash the image using Disk Utility (no third party tools necessary). You also don’t need to format the disk.

The Windows and Linux installers are still working.
