Hello SaiCode,
even though there is no official aarch64-support, there is a workaround for the search container: please use GitHub - hallowelt/docker-bluespice-search at FixArmSupport to build the search image with the same name as required in bluespice-deploy. For aarch64(arm64) you might need to build more images like this, though others won’t have the kind of error that originally blocks docker-bluespice-search. I have tested all of them on my Mac with arm chip, where the latest BlueSpice runs very well.
