Unable to run some docker images showing error "exec format error response from daemon: cannot start container". I have tried running the official image of ubuntu from docker hub.
/ # docker run -it --rm ubuntu:latest
exec format error
Error response from daemon: Cannot start container 8f912fa18ce40551c9754cedb3e065138dc915e9edee283306e19a32c80b8a6c: [8] System error: exec format error

Hi @a-w ,

If you're running on target, you'll need an arm64 container flavor (not x86/64), see this docker file as an example:
