Your Docker installation is not working correctly on Linux/ARM

Support Self-hosting

AI-generated summary

Several users are experiencing issues with their Docker installation on Linux/ARM. Law and jeffsoc report receiving the error “exec format error” and “exec user process caused ‘exec format error’” respectively, when trying to install Discourse on Ubuntu 16.04 and 18.04LTS (arm64). Initially, Falco mentioned that Discourse isn’t supported on arm64 architecture, but later corrected this statement (Falco), citing a recent blog post announcing support for Discourse on ARM architecture, including Raspberry Pi: https://blog.discourse.org/2021/12/2021-12-07-discourse-on-a-raspberry-pi/.

I’ve done a fresh install on Unbuntu 16.04 and even did another fresh one to get the same error below.

Your Docker installation is not working correctly

Hope you can help. I followed the official Discourse install guide.

Thanks :slight_smile:

There has been some issues with ARM infrastructure in the past in which would be worth searching for - such as the following - however you may need some assistance from someone who knows the infrastructure better than myself.

Discourse isn’t supported in arm64 arch, only x86_64.
