Hello everyone,

I’m attempting to install Ignition 8.1.45 on an Ubuntu 22.04 LTS machine with an ARM 64-bit (Raspberry Pi–based) industrial computer. I downloaded the official ARM version (Ignition-linux-aarch-64-8.1.45.zip), unzipped it as instructed, and tried to start it. However, I’m encountering the following errors in my system logs:

Jan 31 22:51:29 ubuntu systemd[1]: Starting Ignition-Gateway...
Jan 31 22:51:29 ubuntu ignition.sh[9085]: Starting Ignition-Gateway...
Jan 31 22:51:29 ubuntu ignition.sh[9160]: /usr/local/bin/ignition/ignition.sh: 1: eval: /usr/local/bin/ignition/./ignition-gateway: Exec format error
Jan 31 22:51:44 ubuntu ignition.sh[9085]: Waiting for Ignition-Gateway..................
Jan 31 22:51:44 ubuntu ignition.sh[9085]: WARNING: Ignition-Gateway may have failed to start.
Jan 31 22:51:44 ubuntu systemd[1]: Ignition-Gateway.service: Control process exited, code=exited, status=1/FAILURE
Jan 31 22:51:44 ubuntu systemd[1]: Ignition-Gateway.service: Failed with result 'exit-code'.
Jan 31 22:51:44 ubuntu systemd[1]: Failed to start Ignition-Gateway.

The logs aren’t very detailed beyond the Exec format error, so I’m looking for advice. Has anyone else run into this issue or found a solution/workaround on a similar setup?

Thanks in advance for your help!

Are you sure the OS itself is 64 bit? There's also different variants of ARM, I remember this being a sticking point but don't remember the specifics.

Ignition ARM 64 runs fine on a Raspberry Pi, as mentioned, you have to be running the x64 Pi image for it to work.
I have run this up really rapidly on a Revolution Pi and can confirm it runs just fine.

Share the output of uname -a to help us confirm.

Thank you all so much for the quick help! You were absolutely right about the 32-bit vs 64-bit issue. I made the rookie mistake of assuming it was 64-bit without actually checking. After downloading the 32-bit version, everything is running perfectly now.

I'm really impressed by how quickly and helpfully everyone responded to my problem. I am very impressed with the Ignition community. Sometimes we just need someone to point out what we're overlooking! Thanks again for snapping me out of my assumption mode and helping me solve this.
