We still don't know what the actual computer you use is :(

Unless it is a (very old) 32 bit only machine, I would recommend

https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.3.0+nonfree/amd64/iso-cd/firmware-11.3.0-amd64-netinst.iso

This is unofficial only because it contains non-free firmware. The firmware
may be necessary for your machine to boot and work well: it will almost
certainly be required if you are installing over a WiFi connection.

The disk listed above is a network install disk: it is small to download
but uses network bandwidth to pull down the rest of the Debian packages
required.

If you can _only_ boot from CD, then you need a program capable of 
burning a .iso to a disk.

If you have a machine running Windows, you can use a program called
Rufus very effectively to write the .iso image to a USB stick.
See also: https://wiki.debian.org/DebianInstall

See also the installation guide at https://www.debian.org/releases/stable/amd64/index.en.html.

I hope this helps. With every good wish, as ever,

Andy Cater.

I am aware that this ISO has non-free packages for a wireless
connection and that any needed will be used and installed by
d-i. However, what about micorode packages, firmware-intel-sound,
bluez-firmwarem and dahdi-firmware? At which stage(s) of an
installation does d-i become aware of them?

Some of these are recognised at inital boot: if unsure, they can be
added. For myself, I normally install the metapackages firmware-linux-nonfree
and firmware-misc-nonfree which solve the problem. As the discussion elsewhere
on Debian mailing lists is showing, it is really very difficult indeed to 
do without all firmware.

The need for a non-free WiFi firmware is recognised and the user is
given the choice to install it or not. I have never come across d-i
offering to install other non-free packages, which is what one would
expect. Are you sure they are even considered?

The "discussion elsewhere" seems to be specifically about firmware
and looks to be going somewhere. About time!

I'm fairly sure that microcode may get installed. As I say, I get round
the problem by installing the two metapackages which pull in everything
needed.

As someone who also works with the images team: I have the highest regard

OK: in many ways that makes it easier. I would still suggest the firmware
disk - if only because that also may include manufacturer's security fixes
for the code that runs deep within the main processor in your machine, for
example.

As Greg says, you can find exactly which firmware you need by runnng the 
command he gave.

If you are happy to rebuild the computer you have with new software -
wiping out the previous attempts to upgrade Debian in place - then:

* Prepare a USB stick / CD with the .iso file.

* Go into the menu which supports boot from different media
[This is sometimes accessed by holding down F1 or F2 or F12 or the Delete key]

* Boot from the install medium and follow the prompts. If you have another
computer available, I would suggest that you also have the release notes
for Bullseye open at the same time -
 https://www.debian.org/releases/stable/amd64/release-notes/

I would suggest the graphical mode install, perhaps.

You said in one of the earliest messages that you have previously been
using Debian LXDE desktop. The first choice for Debian desktop is GNOME
which may use more memory / more resources.

If you wish to use LXDE as your install, when it gets to the screen for
selecting software - deselect GNOME and select LXDE instead. The selections
can be changed by selecting them then hitting the spacebar, I think

Hope this helps.

Dear Sophie,

could you please explain the relation of your planned Debian installation
with Michael Schwibinger. Does he know that you use his name here ?

This list is an international community where humorous statements should be
clearly marked as such, or else they end up in our minds as clueless and
trollish. The german art of Realsatire would be wasted on us, although some
people here may know and love it in real life.

If you are really in distress with the task of installing Debian, then
please consider to find somebody who can guide you through that process
while having physical access to the computer in question.
(Michael Schwibinger himself might be candidate for that.)
Given the level of computer knowledge which you displayed so far and the
informations you gave, i see few chance that any of us remote and globally
scattered Debian users can help you.

Firmware is executable code that runs inside of a device (such as a
network interface) rather than in your CPU.

Many modern devices require some non-free firmware in order to perform
their duties correctly.  This is *especially* the case with wireless
network interfaces, but also applies to video chipsets and other things.

If your devices are old enough, you may not need any.  If your devices
are newer, you probably need some.

You can check by using

  sudo dmesg | grep -i firmware

(or any equivalent way of running dmesg as root).

As for whether it's dangerous... it's kind of a pointless question.  Either
you trust the manufacturer of the device, who is also the author of the
firmware, or you do not.

Firmware can be free OR non-free.

Firmware for wireless interfaces is ALMOST ALWAYS non-free, because of
proprietary secrets that the wireless chip manufacturer is forced to
keep.  The government does not want end users to be able to violate the
frequency restrictions, so they force the manufacturers to keep the
technical details hidden from the users.

Firmware for video chipsets is typically non-free because of trade secrets
that the manufacturers are trying to keep hidden from their competition.

For the love of glob, just FIND OUT WHETHER YOU ARE MISSING ANY FIRMWARE
by running this command:

    sudo dmesg | grep -i firmware

If you are missing some, then GO GET IT!

SHEEEEEESH.

Just FTR, some rather old wired ethernet adaptors, such as the Broadcom
NetXtreme II (BCM5716) in my Dell R210 II, also require non-free
firmware to function:

Modern hardware (wifi adapter for example) is a tiny computer. Firmware is
a special program that runs in it (much like you run Debian on your PC).
Hardware vendors provide firmware as blob: compiled piece of data without
source (like Windows)) so firmware is not open source.
The problem is hardware can't work without firmware, so you still need to
download it and install it inside of hardware.
Since Debian is an open source OS, it doesn't provide closed-source
firmwares by default, and many wifi adapters simply do not work.
To fix that, user must explicitly add "non-free" repository to the list of
apr repositories in Debian (you can do that during installation or later by
editing sources.list) and then
install firmware package.
Debian loads it into hardware and it works after that.

Many people believe that everything (including firmware) must be
opensourced, but we can't force hardware vendors to do that.

There is also a chicken-and-egg problem: you can't access the Internet to
download firmware if your wifi doesn't work. To solve it, one may use
special (unofficial) Debian installer

That depends on your hardware. Most Ethernet hardware
works without firmware.

Are you running as root?
