Raspberry Pi exec format error -out-of-nowhere-

General

since the weekend all my attempts at building in Dockerfiles which were good now fail

“The requested image’s platform (linux/arm64/v8) does not match the detected host platform (linux/arm/v7) and no specific platform was requested”

(NB this is not some bit of cross-wiring to amd64 images, both these are ARM )
and sure enough

I will probably see a exec format error on the next line

The dockerfiles were good when I last built them back in the New Year so something has changed out there

I did try prefixing my build commands with

DOCKER_DEFAULT_PLATFORM=linux/arm64

and have updated my apt packages

Further clarification, it seems that the problem containers are all GO based. I’ll take this enquiry over to another platform
