“docker pull” certificate signed by unknown authority

Question

I was trying to pull a docker image from a docker registry but hit the following issue:

$ docker pull //          


        

Answer 1

For me I ended up doing this to get it to work:

sudo cp -p abc.crt /etc/pki/ca-trust/source/anchors
sudo update-ca-trust
sudo update-ca-trust extract
sudo systemctl daemon-reload
sudo systemctl restart docker
