Hello,

I am new to docker. I have installed docker toolbox in windows 10. first it worked very well. but later when I tried to pull something form hub it display error.

Error response from daemon: Get https://registry-1.docker.io/v2/: x509: certificate signed by unknown authority.

I am searching for solution since last 5 hours. but nothing works.

i have copies the certificates from C:/Users/{username}/.docker/machine/certs to docker machine /var/lib/boot2docker/certs folder and also to /etc/boot2docker/certs.d folder. it’s not working.

Please help. I need the solution urgent. my work is pending due to this.

Hello Muhammad, have you resolved the issue? I do have the same issue. I am not sure where i can get or generate the certification from. Should I use “openssl” to generate a cert for docker.io and import it on the linux machine using “update-ca-trust”?

Thanks
