Architecture not supported when installing 'bullseye' on a 400 model

[SolracLeinad]

Hello!
I'm trying to setup Debian "Bullseye" on this box, and I ran into this problem during the Debian install:

I tried different repos and archive.debian.org as well but I always end up with this error

I know Linux no longer supports "ARMEL" so I really have no clue on what to try next.

I've been looking for answers online but I can't seem to find any. Can you provide any pointers so I can research in the right direction?
Also, is it possible to put the sources in the USB and read them form it? maybe this way I wont need a mirror

Thanks in advance!

Edit:

• buster and strech won't detect the network card.

Search for "install old Debian version" on the net. People reported that there are SSL certificate (expiry) problems and/or the path /oldstable/ is missing or mapped to a wrong debian version. They solved both problems by setting up a local proxy which rewrites /oldstable/ to the correct path.

Please report back if you have a solution so others can benefit from it.

Thanks a lot @hn, I finally managed to complete the installation.

I opted to set up a local repository on a Debian VM and managed to write a script that installs Apache and clones the files needed for a default debian setup.

#!/bin/bash

## Install Apache server and rsync
apt -y install apache2 rsync

## Extract repo_files
echo $REPO_FILES | tr -d '\n\r ' | base64 --decode | zcat | sed -e'1d' -e '$d' > repo_filelist

## Download from repo
rsync -a --include-from repo_filelist --include=*/ --exclude '*' --chown=www-data:www-data rsync://rsync.archive.debian.org/debian-archive/debian $WWW_ROOT


## Cleanup that mess
find $WWW_ROOT -type d -empty -delete
rm repo_filelist

## Create oldstable branch
ln -s "$WWW_ROOT"debian/dists/bullseye/ "$WWW_ROOT"debian/dists/oldstable
chown -h www-data:www-data "$WWW_ROOT"debian/dists/oldstable

MY_IP=$(ip route get 1 | awk '{print $7;exit}')

echo "Your Debian mirror should be reachable at http://$MY_IP/debian"

Finally, we need to update the apt repos to point them at archive.debian after Finish installation:

#/etc/apt/sources.list
deb http://archive.debian.org/debian/ bullseye main contrib non-free
deb-src http://archive.debian.org/debian/ bullseye main contrib non-free

This should do it:
echo -e "deb http://archive.debian.org/debian/ bullseye main contrib non-free\ndeb http://archive.debian.org/debian/ bullseye main contrib non-free" > /etc/apt/sources.list

That's it!
I hope this helps someone out there.

Rsync is creating some files as a Symlink to some hash file. To mitigate this behavior just add the L flag on the download section:

## Download from repo
rsync -a --include-from repo_filelist --include=*/ --exclude '*' --chown=www-data:www-data rsync://rsync.archive.debian.org/debian-archive/debian $WWW_ROOT

I wonder if it is easier not to mirror all files and just use mod_rewrite and mod_proxy:

RewriteRule ^/debian/dists/oldstable/(.*) https://deb.debian.org/debian/dists/bullseye/$1 [P]

(untested, maybe does not work at all)
