Hi @PrimeQH,
Can you maybe share a little bit more context? Which release of Ubuntu, running on which platform, specifically RAM? Plus, why running under root?
Greetz,
Josef
Hi @TheYoctoJester
I have the exact same error. Following the directions Evaluation with Docker Compose | Mender documentation on a Ubuntu 22.04 desktop via ssh (headless). System settings are intel Celeron (2 CPU threads), 16GB RAM.

Hello @petermilani80 
I believe MongoDB might be the issue; starting from version 5.0, MongoDB requires the AVX instruction set for x86_64. Although I would not recommend running software out of a support, the only workaround I think could make it work would be downgrading MongoDB (services.mender-mongo.image in docker-compose.yml) to 4.4. Please keep in mind that this version has been out of support since February this year and won’t receive any further updates.
