Raspberry Pi OS

Raspberry Pi OS "Bookworm" (64-bit) was released 2023-10-11, based on Debian 12. IIAB testing began 2023-04-04 (#3526) and touch-ups were added 2023-10-14 (PR #3660 to resolve systemd-resolved issue #3657) now that the OS is officially released! (As originally announced February 2022, their 64-bit OS now works on Raspberry Pi Zero 2 W, 3, 3 B , 4, 5 and 400.) It's available in a Lite (headless) version or with desktop, and has come a long way since its 2020-05-28 beta.
- ADVANTAGES: "48% faster" than 32-bit. Your IIAB microSD card will also work in newer $15 Zero 2 W computers (if you don't overstress its 512MB RAM!) Also, Calibre e-book software can be installed, making essential commands like calibredb and ebook-convert available to schools building thoughtful e-book collections (whereas it's no longer possible to run
sudo apt install calibre
on 32-bit Raspberry Pi OS "Bullseye" and higher). - DISADVANTAGE: 64-bit IIAB microSD cards won't work in older 32-bit machines like the $10 Raspberry Pi Zero W.
- HEADLESS OPTION: If you choose Raspberry Pi OS "Lite" (instead of "with desktop") and want to install IIAB using a WiFi connection to the Internet (instead of using an Ethernet cable to the Internet) here are instructions to set up Wi-Fi up via the command-line — which expands on the basic headless instructions.
- HISTORICAL: Consider the 64-bit forum discussion and IIAB install tips at #2422.
- ADVANTAGES: "48% faster" than 32-bit. Your IIAB microSD card will also work in newer $15 Zero 2 W computers (if you don't overstress its 512MB RAM!)

-
Raspberry Pi OS "Bookworm" (32-bit) if you really want the original (slower!) Raspberry Pi OS:
- ADVANTAGE: Your IIAB microSD card can work in older $10 Zero W computers (if you don't overstress its 512MB RAM!)
- DISADVANTAGES: JupyterHub and Calibre-Web cannot be installed as of November 2022. Also, Calibre e-book utilities cannot be installed. In addition, Node.js applications like Internet Archive, JupyterHub, Node-RED, PBX (Asterisk/FreePBX) and Sugarizer won't work on Raspberry Pi Zero W (ARMv6) if you installed Node.js while on RPi 3, 3 B (ARMv7) or RPi 4 (ARMv8). Read IIAB's Node.js tips if you want to try to make one of the apps work on Zero W.
- WARNING: The Raspberry Pi's older NOOBS OS IS NOT SUPPORTED.

Ubuntu 24.04.1 LTS (Noble Numbat) originally released 2024-04-25, works well on PC (amd64), or more experimentally on Raspberry Pi (tutorial, install guide). #3662
- If you absolutely must install IIAB using a Wi-Fi connection to the Internet (instead of an Ethernet cable to the Internet) then before you first boot Ubuntu on Raspberry Pi, you should: (A) Enter your building's Wi-Fi SSID and password using Raspberry Pi Imager's Advanced Options (in the past they recommended editing the pre-existing network-config file, at the top-level of the microSD card). (B) Boot the microSD card in your Raspberry Pi, log in, and run
sudo mv /etc/netplan/50-cloud-init.yaml /etc/netplan/02-iiab-config.yaml
. (C) Finally, your IIAB should contain just these 2 files in /etc/netplan (ideally!) if you choose to abide by recommended norms — if so create/edit them (with your building's actual SSID and password) to appear as in these 2 examples:-
/etc/netplan/00-installer-config.yaml
or/etc/netplan/01-iiab-config.yaml
should contain the "ethernets:" section:network: ethernets: eth0: dhcp4: yes optional: true
(You might need to change
eth0
above, to the actual Ethernet interface name shown by theip addr
command. ALSO PLEASE READ #3385 CAREFULLY, IF ATTACHING AN EXTERNAL WIFI DEVICE!) -
/etc/netplan/02-iiab-config.yaml
should contain the "wifis:" section — populated with your building's actual WiFi-to-Internet SSID and password:network: wifis: wlan0: dhcp4: true optional: true access-points: ACTUAL-SSID: password: ACTUAL-PASSWORD
(You might need to change
wlan0
above, to the actual Wi-Fi interface name shown by theip addr
command.) -

- Raspberry Pi OS "Bullseye" (based on Debian 11) e.g. 64-bit with desktop or 32-bit Lite if absolutely necessary.
-
Raspberry Pi Desktop for PC a.k.a. Debian Bullseye with Raspberry Pi Desktop (for PC, x86_64 VM, or Mac) will NOT work with modern Node.js apps — as a result of this distro's hybrid 32-bit and 64-bit CPU arch legacy (specifically, i386-instead-of-amd64 versions of python3 packages) which lead to serious Node.js 10.x problems across the board. Sugarizer can be made to work if absolutely necessary. But this is ENTIRELY AT YOUR OWN RISK. Extensive details written up on 2021-07-21: #2873
- Manually install Node.js and npm, running these 2 lines as root: (for roles/internetarchive, roles/jupyterhub, roles/nodered, roles/pbx i.e. Asterisk/FreePBX and/or roles/sugarizer)

Ubermix 4.x based on Ubuntu 18.04
- Create a USB stick (USB drive >= 4GB will suffice initially) to install Ubermix 4.x. Download the latest from http://ubermix.org/files.html and follow the instructions at http://ubermix.org/download.html
- Read the "Customization Overview" section here: http://ubermix.org/customization.html. This is important information to understand.
- Use your Ubermix USB install stick to do an ADVANCED install of Ubermix 4.x on your designated computer (turn off UEFI in its BIOS if possible) following the instructions under "Installing on your System" here: http://ubermix.org/download.html
- You need to shrink the /home partition to make room for content to be stored in /library. Change partition sizes by selecting Option 2 ("Advanced image") to set a larger size for the Default System partition (/dev/ext2) and/or larger size for the User Changes partition (/dev/ext3). You will be prompted to manually enter in partition sizes.
- e.g. for an 80GB hard drive, consider 12GB (default) for the Default System partition and 50GB for the User Changes partition (IF /library IIAB content will be stored in the User Changes partition, wiped during factory reset reverts). You can adjust the partition sizes as necessary based on your hard drive size and content size needs.
- e.g. consider reversing this: 50GB for the Default System partition and 12GB for the User Changes partition (IF /library IIAB content will be stored in the Default System partition, to protect it from factory reset reverts)
- Ubermix will install in ~5 or so minutes.
- You need to shrink the /home partition to make room for content to be stored in /library. Change partition sizes by selecting Option 2 ("Advanced image") to set a larger size for the Default System partition (/dev/ext2) and/or larger size for the User Changes partition (/dev/ext3). You will be prompted to manually enter in partition sizes.
- Once Ubermix is installed and you are logged in, confirm the partitions are as you expect by opening up the Terminal and entering "df -h". Proceed if all is as expected.
- Turn off aufs (UnionFS). Follow steps #2-6 under the "Rebuilding the Base Image" section here: http://ubermix.org/customization.html
- Congratulations, you are now ready to install IIAB.
- Install curl, by manually running: sudo apt install curl
- Run IIAB's 1-line installer: https://download.iiab.io
- Turn aufs (UnionFS) back on.
- Consider building a USB stick to install everything at once onto other laptops/desktops, reading "Rebuilding the Base Image" in http://www.ubermix.org/customization.html ("5. Expert Options", then "1. Update the image on the key using this machine as a model")
- Ubuntu Server 19.10.1 for Raspberry Pi released 2019-12-05 (docs, downloads). Stick with the 32-bit version for now, until 64-bit Kiwix support appears (kiwix/kiwix-build#396). Please do not install or enable Sugarizer in /etc/iiab/local_vars.yml as this OS lacks MongoDB.

These warnings are harmless, but FYI if you've installed IIAB Apps like Sugarizer or Internet Archive, then commands like apt update
will warn you every time: "Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details."
- Subsequent runs of
sudo iiab
are no longer blocked (byapt update
warnings about/etc/apt/trusted.gpg
) as of November 2022, thanks to PR iiab/iiab-factory#236. - Still, if you want to eliminate these apt warnings after installing Sugarizer (and hence MongoDB), run:
It will delete the key and warn you:
apt-key list rm /etc/apt/sources.list.d/mongodb-org.list apt-key del 90CF B1F5
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
- Likewise if you installed roles/internetarchive and hence yarn (e.g. as part of a LARGE-sized IIAB install), you can run:
rm /etc/apt/sources.list.d/yarn.list apt-key del 86E5 0310
Theoretically Internet-in-a-Box (IIAB) should run on any machine that can run Ubuntu, Debian or close derivatives (like Raspberry Pi OS, Linux Mint, Ubermix, etc).
In practice, IIAB has been tested on the platforms and configurations below. For more detail, see "What hardware should I use?" within FAQ.IIAB.IO
2GB RAM (or higher) is preferred, but 1 GB RAM (or even 512 MB RAM) can still work on a Raspberry Pi if you carefully build your IIAB without too many apps/services, right-sized for a small community's needs.
Typically a microSD card of 32, 64, 128 or 256 GB will be used, though SSD's have been tested experimentally. Also the Raspberry Pi's 4 USB ports can allow for Ethernet dongles, external Wi-Fi, and possibly additional storage.
(And after building your Internet-in-a-Box microSD in a Raspberry Pi 3, 3 B , 4 or 400, also consider testing it within the amazing/tiny 512MB Raspberry Pi Zero W, sometimes available for as little as $3.14 at Micro Center stores in the USA. Likewise consider the much faster $15 Raspberry Pi Zero 2 W released on 2021-10-28.)
Mini PC's also include MSI and Zotac etc, typically configured with 4 to 8 GB RAM and a 1TB internal hard disk, or 200 GB SSD. Most models have a minimum of four USB ports and some have an internal Wi-Fi adapter.
A number of implementers have successfully deployed IIAB on late model desktop and laptop computers.
Virtual machines (VM's) with varying configurations, especially Ubuntu and Debian, are often used for testing and proofs-of-concept.
In the past, IIAB was run on One Laptop Per Child (OLPC) laptops, typically with an SD card of 32, 64, or 128 GB, e.g. with a subset of the content found on machines with more storage, or with an external hard drive.
FYI this used Fedora 18, building on the OLPC OS.
Disable UEFI in your computer's BIOS if possible!
It's critical to avoid a large /home partition, so there's room to add content (in /library). Pay close attention while installing your OS (Ubuntu, Debian etc). You should remove (or dramatically shrink) this /home partition, if your Linux distro insists on creating one.
On a 1 TB disk, we recommend the following 2-to-4 partitions, such as: (traditionally we use standard partitioning, but now increasingly LVM partitioning is also possible)
- /boot - 500 MB
- swap - 2 GB (optional partition, set this to your RAM size, or create a swap file if you prefer)
- / - 50 GB
- /library - the remainder (optional partition, can protect your content during major upgrades)
On smaller disks and SD cards, also consider:
- reducing (or altogether eliminating) the swap partition — see variable
pi_swap_file_size
in /etc/iiab/local_vars.yml - avoiding a separate partition for /library — far better to keep your content directory (/library) within the main partition!
Each of the above devices may have one or more network adapters. These may be internal Ethernet, internal or external Wi-Fi, or Ethernet dongles. The role the server is able to play in the network will depend on what adapters and connections it has.
