CA 問題

執行 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
時會遇到 x509, unknown authorit 的問題
apt update 會有 CA 的問題

Download CA











# 首先把對方網站的 certification 抓下來
$ echo -n | openssl s_client -connect download.docker.com:443 -showcerts | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > docker.crt

# 利用抓到的 certification 去抓取 docker 的 gpg
$ curl -fsSL --cacert docker.crt https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

# 安裝 certification 在自己電腦上 之後才可以 apt update
$ cp docker.crt /usr/local/share/ca-certificates/
$ apt update ca-certificates
