Raspberry Pi Model B: Setup Raspbian Wheezy SD Card using Debian Bullseye PC

 

Raspberry Pi (c)2011.12 is very old and slow machine. I decided to reinstall the OS using legacy one, i.e. Wheezy version (End of Support).

On Debian Bullseye PC

Download Raspbian Wheey image from http://downloads.raspberrypi.org/raspbian/images/raspbian-2015-05-07/
and extract it

$ unzip 2015-05-05-raspbian-wheezy.zip

Insert SD Card and check SD Card

# dmesg
...

[ 2556.197858] sd 1:0:0:0: [sdb] Mode Sense: 03 00 00 00

The SD Card is at sdb

Warning: Careful to select disk, this command will erase all of your data in sdb.

# umount /dev/sdb
umount: /dev/sdb: not mounted.
# dd bs=4M if=/home/dedetok/master/raspbian/2015-05-05-raspbian-wheezy.img of=/dev/sdb status=progress

On Raspberry Pi Model B

Insert your SD Card into Raspberry Pi Model B, mouse, keyboard, HDMI/TV and Power your Raspberry. Running and configuring Raspbery Pi 2 Model B for the first time will show these menu

1. Expand File System
2. Change User Password
3. Enable Boot to Desktop/Scratch
4. International Options
5. ....

You need to:

  1. Expand File System option 1
  2. Change user (default user is pi) password option 2
  3. Change boot to desktop if you wish option 3

You can alter this configuring later by running

$ sudo raspi-config

Raspbian Wheezy support has been terminated and repository was moved to legacy http://legacy.raspbian.org/. To update your Raspbian Wheezy you need to:

  1. edit /etc/apt/sources.list
    deb http://legacy.raspbian.org/raspbian wheezy main contrib non-free rpi
    #deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
    # Uncomment line below then 'apt-get update' to enable 'apt-get source'
    #deb-src http://archive.raspbian.org/raspbian/ wheezy main contrib non-free rpi
  2. edit /etc/apt/sources.list.d/raspi.list
    #deb http://archive.raspberrypi.org/debian/ wheezy main
    # Uncomment line below then 'apt-get update' to enable 'apt-get source'
    #deb-src http://archive.raspberrypi.org/debian/ wheezy main
  3. edit /etc/apt/sources.list.d/collabora.list
    #deb http://raspberrypi.collabora.com wheezy rpi

You need to download and install legacy repository public key for raspbian wheezy

$ wget http://legacy.raspbian.org/raspbian.public.key
$ sudo apt-key add ./raspbian.public.key
OK

To update your system run:

$ sudo apt-get update
$ sudo apt-get upgrade -y

By default, root user is disable. To enable root and login as root

$ sudo passwd root
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
$ su -
Password:
#

You do not need to type sudo for manage your system. After that you don't need monitor, keyboard and mouse, you can ssh your Raspberry Pi.

Note: By Default SSH Server is enable and running after boot

Running on:

  • Raspberry Pi (c)2011.12 Model B+ Revision 1.0
  • SD Card 8Gb
