Hi, I was going to see if the network installation image would work successfully to reinstall debian 11.00 with non-free firmware needed for my network cards. When I ran the installer at low priority so everything would work as expected and so I would have full control of the installation when
it got to the firmware loading it fails to load the firmware for any of my network cards when before on this same system in earlier versions of debian it worked just fine. Attached is the syslog from the installer. Can
someone please tell me what is going on with this installation image? Nick Gawronski

Hi,

This is the official Debian media installer

Try the unofficial non-free CD : from the lines I've selected, it looks as
if you might be able to install via wired interface without loading firmware.

Otherwise - you need to install firmware-iwlwifi for the wireless card

You might want to install:

firmware-linux-nonfree firmware-misc-nonfree firmware-iwlwifi to ensure
that you've got everything.

The unofficial installer including non-free firmware is at:

https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/current/amd64/iso-cd/firmware-11.0.0-amd64-netinst.iso

Hope this helps. With every good wish, as ever,

Andy Cater

Hi, Yes as I looked and it appears as if the firmware package is on the
network installation image.  This system has debian already installed on
it is there a way I could send you the installation report from this
system so you could take a look at it like where is it stored on the
system?  Nick Gawronski

Hi Nick,

Nick Gawronski <nick@nickgawronski.com> (2021-09-15):

See the logs:

Feb 25 15:44:44 check-missing-firmware: missing firmware files (iwlwifi-6000g2b-6.ucode iwlwifi-6000g2b-5.ucode) for iwlwifi

Feb 25 15:44:50 main-menu[611]: (process:5046): ar: short read
…

and various other failures afterwards.

I'm not sure the installation image is available on a decent medium. The “short read” could be due to problems reading back data from the medium (initial copy was problematic, or future uses are problematic). I'd
probably try with something else (different CD/DVD, or different USB
stick).

Also, Feb 25 seems strange (even if I reckon you might not be able to
have NTP up and running without networking, I'd expect a reinstall to
know about some less crazy time via the RTC… but then I didn't check the exact ordering in install steps… just mentioning this in passing since
it caught my eye).

Hi, I just tried this same process with the debian non-free DVD and
educational versions with the same results.  My system was installed
with an earlier version of debian-installer so where can I locate the installation report on my system as sending this to you might help?

So, that's how it looks like, when it works.
Don't be irritated by that many line like
"mount: mounting /dev/sda on /media failed: Invalid argument"
That's just because there a (maybe not-that-smart) logic, which tries to mount any possible devices, to find a media which contains firmware files.

In your "failed installation" syslog file, you have many lines like
Feb 25 15:44:50 main-menu[611]: (process:5046): ar: short read
Feb 25 15:44:50 main-menu[611]: (process:5046): ar: short read
Feb 25 15:44:50 main-menu[611]: (process:5046): ar: short read
Feb 25 15:44:50 main-menu[611]: (process:5046): ar: short read
Feb 25 15:44:50 main-menu[611]: (process:5046): ar: short read
Feb 25 15:44:50 main-menu[611]: (process:5046): ar: short read
at the point, where it should try to mount those devices.


Thus, as kibi already wrote, there seem to be problems reading the media
or similar.
So try to write to another USB stick or another DVD, as kibi already wrote...
