Test download failed with certificate error: SSL certificate problem: unable to get local issuer certificate (curlcode 60)

Description

Due to a problem in the Quartus® Prime Installer Software, you might see the error message stated above when you click Download & Install. This happens because the certificate bundled with the Quartus® Prime Installer Software is no longer accepted by the Altera® Content Delivery Network (CDN). As a result, secure downloads initiated during the installation process cannot be verified using the outdated certificate.

Resolution

To work around this problem, follow these steps: 

1. Download and unzip cacert.zip, which contains the cacert.pem certificate file.

2. Specify the new certificate using one of the following methods:

i) Command Line Interface (CLI):
Open a command prompt or terminal and run the installer with the --cacert option, pointing to the new certificate file

Windows*:

qinst_<version>.exe -sp"--cacert <full path to cacert.pem>"

Linux*:

qinst_<version>.run -- --cacert <full path to cacert.pem>

ii) Graphical User Interface (GUI):
- Open the Quartus® Prime Installer, navigate to Settings, locate CA Certificate Path, and specify the full path to the cacert.pem certificate file.
- Then, click Apply > OK.

This problem is scheduled to be resolved in a future release of the Quartus® Prime Installer Software.
