#230551 — MacOS Big Sur balenaEtcher Bug

Hello,

I downloaded the debian-10.7.0-amd64-netinst.iso image from the home 
page on Big Sur. I tried to flash it with balenaEtcher and am running 
into problems. When the flash is complete in balenaEtcher, it says files 
cannot be read by the system and when I look at the size of the USB 
bootable it becomes like 2-3 MB and looks corrupted.

Nevertheless, I booted into the debian installation and the interface 
does appear showing "Install Debian" although the screen is zoomed out 
really far. When I hit enter and it brings up the select language screen 
in the Debian installation, the screen is still zoomed out really far 
and the mouse or keyboard are unresponsive.

Any thoughts or ideas?


Configurations:
Big Sur 11.1

Partition Map: MBR

Mac OS Extended (Journaled)


Thanks,

Stephen

I suspect corruption during downloading. Did you check the checksums?
https://www.debian.org/CD/faq/#verify For the checksums,
https://cdimage.debian.org/cdimage/release/current/amd64/iso-cd/

I'm no expert on Macs, but I see on that page
debian-mac-10.7.0-amd64-netinst.iso. Are you getting the right
architecture?

That image was for a limited subset of Intel based Macs some years ago - see
various discussions elsewhere in this list. The AMD64 image should work for 
current Intel-based Macs.

If you're prepared to pay for software for your Macs, VMWare and Parallels
both support Debian well.

Hope this helps,

Andy C.

Thanks for that clarification.

One other thing that might be relevant: you're on the very latest iteration of
MacOS. Few of us are guaranteed to use Macs necessarily: if your Mac uses behaviour/features in the new MacOS that we don't yet know, there may yet be
things we need to learn.

All the very best, as ever,

I decided I think it's best to purchase the new Librem 14 for Debian 
since it's built for Linux once I get another job that is. (unemployed) 
It's costly...$3,500-$4,000.

What I do in such situations is buy a refurbished laptop. Not as
shiny, but one-tenth the price for (perhaps) half the performance.

At the moment I'm on a refurbished thinkpad 230, which I topped
up with 16 GB RAM and 1T harddisk.

Debian... and I'm happy as a clam :)

Cheers

It might be that balenaEtcher interprets too much.
Probably it shows only the EFI System Partition which is 2832 KiB size.
The ISO partition has type 0x00 to hide it from EFI which would hate that
it encloses the EFI partition.

This indicates that the early stages of booting work, including the stage
when the ISO filesystem is mounted to make the installation files accessible.

This looks like the installation files are not fully suitable for the
machine. A very broad statement, i confess, and not pointing to any
remedy, i fear.

This text talks of "optical media" (e.g. /dev/sr0) but also applies to
USB sticks and other disk-like storage devices (e.g. /dev/sdc).
Important is to read from the device exactly the same amount of data
as the copied ISO image file has.
Nearly all storage media will return more bytes that were written from
the ISO image file. Those extra bytes would spoil the checksum.

The "mac" ISOs just lack EFI equipment, which is said to confuse some
older Macs. They contain no special Mac software.
Since Stephen's USB stick booted, i think that the normal BIOS+EFI
netinst ISO is the right thing to use.


Have a nice day :)

Thomas
