Bitcoin Core

Official Download Page: https://bitcoin.org/en/download

For 32-bit ARM Linux, the download link is:

https://bitcoin.org/bin/bitcoin-core-0.21.1/bitcoin-0.21.1-arm-linux-gnueabihf.tar.gz

Fore auto update, use snap store instead.

# From https://snapcraft.io/install/bitcoin-core/raspbian
# Install snap
sudo apt update
sudo apt install snapd
sudo reboot
sudo snap install core

# Install bitcoin-core
sudo snap install bitcoin-core

List info to see how can I launch bitcoin-core.

$ snap info bitcoin-core

...
commands:
  - bitcoin-core.cli
  - bitcoin-core.daemon
  - bitcoin-core.qt
...

Snaps are installed in /snap/bin but I get the error

$ /snap/bin/bitcoin-core.cli -version
ERROR: ld.so: object '/usr/lib/arm-linux-gnueabihf/libarmmem-${PLATFORM}.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file): ignored.
ERROR: ld.so: object '/usr/lib/arm-linux-gnueabihf/libarmmem-${PLATFORM}.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file): ignored.
ERROR: ld.so: object '/usr/lib/arm-linux-gnueabihf/libarmmem-${PLATFORM}.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file): ignored.
Bitcoin Core RPC client version v22.0.0

But this one works. Seems the binary published to snap store supports 32-bit but snap itself don't.

$ /snap/bitcoin-core/current/bin/bitcoin-cli -version
Bitcoin Core RPC client version v22.0.0

So my PATH be like

export PATH=/snap/bitcoin-core/current/bin:/snap/bin:$PATH

Upgrade Raspberry Pi OS from buster to bullseye by ChatGPT

As of my last training data cut-off in September 2021, the process to upgrade your Raspberry Pi OS from "Buster" (Debian 10) to "Bullseye" (Debian 11) would follow similar steps to other Debian-based system upgrades.

Here is a general outline of the steps you'd take:

Step 1: Make a backup

Before you begin, it's essential to back up any important data. System upgrades have the potential to go wrong, and it's always better to be safe than sorry.

Step 2: Update your current system

First, update your existing system packages to their latest versions. To do this, open a terminal and type:

sudo apt update
sudo apt full-upgrade

This will update the package list and upgrade all packages to their latest version. The full-upgrade command will also handle any dependencies, removing obsolete packages if necessary.

Step 3: Modify your apt sources

You will need to modify the /etc/apt/sources.list file and change all instances of 'buster' to 'bullseye'. You can do this manually with a text editor or use the sed command in terminal:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak  # Backup your sources list
sudo sed -i 's/buster/bullseye/g' /etc/apt/sources.list

If you have additional software sources set up in separate files under /etc/apt/sources.list.d/, you should also update those files:

sudo sed -i 's/buster/bullseye/g' /etc/apt/sources.list.d/*.list

Step 4: Perform the upgrade

You can now proceed with the upgrade by running:

sudo apt update
sudo apt full-upgrade

This will update your package list with the Bullseye repositories and perform the upgrade.

Step 5: Clean up

After the upgrade, you may want to remove unnecessary packages:

sudo apt autoremove
sudo apt autoclean

Step 6: Reboot your Raspberry Pi

Finally, reboot your Raspberry Pi to make sure everything is working as expected:

sudo reboot

NOTE: This is a general guide. The specific steps may vary based on your particular configuration and the specific versions of the OS. It's crucial to back up your data before performing an OS upgrade, as things can occasionally go wrong. Proceed with caution and consult the official documentation and community if you encounter problems or have concerns. It's often also a good idea to test this process on a secondary device first, if one is available.
