When running

docker buildx build --platform linux/arm64,linux/amd64,linux/arm/v7 -t my-project .

it fails with a very cryptic error message:

------
 > [internal] load build context:
------
error: failed to solve: snapshot  does not exist: not found

which I can't find in google.

This is on debian, I just switched from debian's docker.io for the docker-ce package to get buildx support.

CodePudding user response：

This cryptic error is shown when using docker buildx with a buildx-capable docker command, but with the docker service still being the old non-buildx-capable one.

Manually restart the docker service with

service docker restart

(or similar, depending on your service system) and buildx will work just fine.
