How to install 32-bit BOINC on my 64-bit Raspberry Pi?

By Nickwasused at

Why would you do this?

  • Projects like UNIVERSE@HOME have no aarch64 Tasks.
  • A Raspberry Pi 3b can´t run ROSETTA@HOME because it doesn't have enough ram.
  • DietPi, a popular OS for the raspberry pi, uses 64Bit.


  • 64-bit raspberry pi e.g. DietPi


uname -a

the output should contain the following: aarch64 if there is armhf in the output then you can skip to the [Install]({{< ref "#install-32-bit-boinc" >}} "Install") section. Example output: Linux raspberrypi-1 5.10.103-v8+ #1530 SMP PREEMPT Tue Mar 8 13:06:35 GMT 2022 aarch64 GNU/Linux


First, we need to add the 32-bit Architecture to our system with the following command:

sudo dpkg --add-architecture armhf

Now you need to update the package list:

sudo apt update

Remove 64-bit Boinc

To remove the 64-bit version of the Boinc-Client type:

sudo apt remove boinc-client -y

Install 32-bit Boinc

If the output of uname -a is armhf then type:

sudo apt install boinc-client

To install the 32-bit version of the Boinc-Client type:

sudo apt install boinc-client:armhf -y
