Installing OPM in CentOS 8.1 (RPM).

[suporte-unisim]

Hi

I'm trying to install OPM on CentOS 8.1 using the available repository, but when I run the first command to install the repository, I get an expired certificate message. Below the message:

sudo yum-config-manager --add-repo
https://www.opm-project.org/package/opm.repo

Failed to set locale, defaulting to C.UTF-8
Adding repo from: https://www.opm-project.org/package/opm.repo
Curl error (60): Peer certificate cannot be authenticated with given CA certificates for https://www.opm-project.org/package/opm.repo [SSL certificate problem: certificate has expired]
Error: Configuration of repo failed

Can someone help me perform this installation please.

Thanks
