easy-rsa not working with openssl 1.1

[Xavier Poinsard]

/usr/share/easy-rsa/whichopensslcnf script is not working when openssl 1.1.X is installed.
The script does not expect a version greater than 1.0.Xy
As a workaround, a openssl.cnf can be created manually from openssl-1.0.0.cnf

Status changed to 'Confirmed' because the bug affects multiple users.

[Johan Ehnberg (johan-ehnberg)]

Here is a one-line to work around the issue:
    sed -i 's#export KEY_CONFIG.*#export KEY_CONFIG="$EASY_RSA/openssl-1.0.0.cnf"#' /home/ubuntu/openvpn-ca/vars

[Jacques-D. Piguet (jacques-piguet)]

Same problem, using the command below as workaround:
   ln -s openssl-1.0.0.cnf openssl.cnf
