Hi everyone,

When trying to pull a image from the docker hub, I am recieving some weird errors. The specific error that the docker daemon returns is:

“Error getting v2 registry: Get [https://registry-1.docker.io/v2/:](https://registry-1.docker.io/v2/:) x509: certificate signed by unknown authority”

The weird thing is that running “docker search x” runs fine and returns what was expected. Also curling the page(curl -vL [registry-1.docker.io](http://registry-1.docker.io)) and running the openssl s\_client(openssl s\_client -connect [registry-1.docker.io:443](http://registry-1.docker.io:443)) doesn’t return any certificate errors.

I am not behind a corperate proxy or anything like that. I’ve tried a lot of solutions like adding certs to the /etc/docker/certs.d directory, rebooting my machine, and almost everything that google searches suggested.

My docker version:  
Client:  
Version: 1.12.2  
API version: 1.24  
Go version: go1.6.3  
Git commit: bb80604  
Built: Tue Oct 11 17:00:50 2016  
OS/Arch: linux/amd64

Server:  
Version: 1.12.2  
API version: 1.24  
Go version: go1.6.3  
Git commit: bb80604  
Built: Tue Oct 11 17:00:50 2016

Thanks!
