Unexpected reboot after powerpc install

2021-02-09 Thread Jeffrey Walton
Hi Everyone,

I was trying to follow John Paul Adrian Glaubitz instructions for
installing Debian 10 on a PowerMac G5. The instructions are at
https://lists.debian.org/debian-powerpc/2021/02/msg00011.html. The
instructions say to forgo the reboot after installation and perform
some extra steps.

At the end of the installation, the last screen told me a reboot was
needed. The last screen gave me two choices -  or .
I selected  because I had the extra steps to perform. I
planned on reboot after performing the extra steps.

 unexpectedly rebooted the machine and I lost the chance to
perform the extra steps. (Now I'm stuck at an OpenFirmware prompt that
results in a kernel load failure/corrupt image error message for every
command I enter. Sigh...)

>From a UX perspective, the last screen has a lot of opportunity for
improvement. There's no indication what  does or where it
"goes back" to. It is also not clear that "going back" does not undo
the most recent steps performed by the installer. Finally, there's no
indication  will immediately reboot the machine.

I believe the last screen should say something like:

Installation is complete. A reboot is required.
If you select  then a reboot will happen now.
If you select  then you will have to manually
reboot later.

Would you like to Reboot now?



Changing the text on the last screen will dramatically improve the UX
experience. It tells the user what is going to happen. It also offers
the user a chance to avoid the reboot .

Actually, at the reboot step, you need to "Switch to another console".

See (1) on how to do that.

Well, you can just select "Go back" and you're in the main menu from where
you can also execute a shell.

I have backed up the user data, but I am not at all sure how to

it to a specialist with a copy of the user data.


I suggest at this point you should try out one of the debian "live" images.
These can be copied to a USB stick (via win32diskimager or others) just like you
copied the installer to USB.  Then, you boot into the live image and it runs
completely from the USB stick -- you have a mostly complete linux system you can
experiment with, without permanently writing it onto any other disks, and
without the live system needing to write to any other disks.

I would suggest the current stable "gnome" live system, which is familiar to
Windows users -- and I also suggest the so-called "non-free" version (which just
means it includes various firmware files for wifi or fancy graphics adapters,
etc.)

Download here:
https://cdimage.debian.org/cdimage/unofficial/non-free/images-including-firmware/current-live/amd64/iso-hybrid/debian-live-10.8.0-amd64-gnome+nonfree.iso



I am going to try your suggestion.

For the record, I did fully reinstall Debian with Fastboot (both Windows 
and BIOS) disabled.  I got the same issues as before, but can confirm 
(because I was looking for it) that the installer/partitioner does not 
seem to see the SSD.

It could see both the install USB flash drive and the external USB HDD.

Installing firmware and ISO images on CD/DVD

2021-02-09 Thread Jeffrey Walton
Hi Everyone,

I'd like to install the additional firmware required for PowerPC. It
is briefly discussed at
https://www.debian.org/releases/jessie/amd64/ch06s04.html.en.

The problem I am having is, PowerMac's don't have an eject button. I
can't eject the installer to add the firmware CD from
http://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/archive/8.10.0+nonfree/powerpc/iso-cd/.
I tried to use a USB stick but the firmware was not found. (I don't
even think the USB bus was scanned - the led on the usb stick did not
blink).

I think the installer should be modified in two places to support an
eject operation. The first place is the "Missing firmware" screen. The
second place is the "Configure Apt" screen.

Jeff

You can eject the CD from the command line with:

# eject /dev/cdrom

or

# eject /dev/sr0

That could potentially be done but we‘re adding firmware on the ISOs in the 
near future anyway.

Color choices for the installer

2021-02-09 Thread Jeffrey Walton
Hi Everyone,

I think the installer's choice of red for the background color can be
improved. Red is a color associated with anger and aggression. Red as
an accent would probably be OK, but the installer uses a wall of red.

There's no need to increase anger and aggression when working with an
installer. I know of a couple of companies that changed their colors
to avoid red to reduce stress and anxiety in its customers. For
example, USAir.

Blue is usually a safe color. It is favored by most people. It is
associated with calm, serenity, stability and reliability. There are
other colors available if you are not a fan of blue.

The only time you'd normally get a red background is when the
installer is flagging an error.

Thanks Steve.

Yeah, I kind of feel that way. After 9 hours of trying to install
Debian I'd write it up as one big mistake. I think I'll wait for the
release ISO.

I'm doing all this in my free time and I'm working on the Debian Ports
releases almost alone. But thanks for the praise anyway.

The second CD you reference [8.10.0+nonfree] is both an installer and a source
of firmware files.  You should be able to install without ejecting, I think?

2021-02-09 Thread Josef Hahn
Package: debootstrap
Version: 1.0.114
Severity: normal

I'm struggling with a problem that I currently have with debootstrapping an
arm64 system on my amd64 machine. The attached script can reproduce the issue
here.

It crashes here on a debian buster amd64, in the 2nd debootstrap stage:

It works if I debootstrap a buster system instead. Then trying to upgrade to
bullseye in the same chroot crashes with a segfault during the upgrade of libc-
bin. It also segfaults when I just open a chrooted shell after the 1st stage
and then run "ldconfig". That worked here around new year, but then broke.

This looks like a software bug somewhere. I'm not sure if I'm right here. But
maybe you can tell me.

Yes, I think that's what it does implicitly due to some magic
mechanism. I can also explicitly write 'qemu-aarch64-static' in front
of '/bin/bash' in my script, but that seems to do the very same thing.

Interesting indeed. But do you think it could be related? Well, I'll
give it a try tomorrow. Interesting improvement anyway.

I would not like to switch to just another tool at that moment. My
actual script is a bit larger and would not be trivial to migrate.

Something seems to break regarding libc-bin, so is this about glibc in
some way? Sorry, I'm not deeply experienced in those system levels. :)
What would be good ways to get more information? I tried with strace
meanwhile, but this is just telling me "PTRACE_TRACEME: Function not
implemented". :-/

As I said, I definitely had it working here, one or two month ago,
without changes on the script. So I'm optimistic that it could be
solvable.

That's great to hear. So even if I cannot get it solved, it should go
away in some months. :) Not perfect, but not worst case...
