The trick is to add environment variables to sudoers file via sudo visudo command and add these lines:

Defaults env_keep += "ftp_proxy http_proxy https_proxy no_proxy"

On Fedora since 19, RHEL / CentOS 7, and RHEL / CentOS 6 since this update, the Shared System Certificates feature is available. With that system, the correct method is to place the certificate to be trusted (in PEM format) in /etc/pki/ca-trust/source/anchors/ and run sudo update-ca-trust. (If the certificate is in OpenSSL’s extended BEGIN TRUSTED CERTIFICATE format, place it in /etc/pki/ca-trust/source).
