Certification issue while installing rvm on ubuntu 16.04

Question

When I am trying to install RVM, on Ubuntu 16.04. I am getting a certificate verification issue. Please find the below screenshot for reference. Is that happened because of firewall or is it is related to RVM?

Please escape me from this issue. Thanks in advance.

curl -sSL https://get.rvm.io | bash -s stable

Answer 1

为了获得rvm所需的公钥，你需要安装gnupg

sudo apt-get install gnupg gnupg2

然后您就可以安装公钥

了

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

现在你可以安装rvm

了

\curl -sSL https://get.rvm.io | bash -s stable
