installing: XYZ cannot register "/usr/bin/qemu-XYZ " to /proc/sys/fs/binfmt_misc/register: write /proc/sys/fs/binfmt_misc/register: invalid argument

[gasgithub]

Hi,

I'm trying to install qemu in docker.io/library/docker:19.03.14 container (Linux reynwz-containerize-pod 3.10.0-1160.62.1.el7.x86_64 #1 SMP Wed Mar 23 09:04:02 UTC 2022 x86_64 Linux) running the following but getting errors:

docker run --rm --privileged tonistiigi/binfmt:latest --install all

but getting following errors:

    "linux/amd64",

Any hints why it fails to register? What can I do to fix this issue?

I also tried running

I just created moby/buildkit#2957 which is similar if not the same.

[marcelstoer]

Do you have kernel >=4.8?

Had same error, my kernel is version 3.10.108 (uname -r on a synology) @marcelstoer
