With the latest version of RStudio Connect, you may receive this error message: 

Error deactivating product key: (4): Connection to the server failed. Ensure that you have a working internet connection, you've configured any required proxies, and your system's root CA certificate store is up to date; see https://rstudio.org/links/licensing_ssl for more information 

To resolve the issue, please update your list of trusted certificates.

Updating the Trusted Certificates

     To update on CentOS / RHEL:

 

 sudo yum update ca-certificates

 

     To update on Debian/Ubuntu:

 

 sudo apt-get install --reinstall ca-certificates

 

If the error persists, you can manually install the CA certificate.

Manually Installing the CA Certificate

 

To retrieve the root CA and store to rstudio-license.crt, use the following command from the shell.

 

echo | openssl s_client -showcerts -connect wyday.com:443 2>&1 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' | tail -n 32 > rstudio-license.crt

 

 On RHEL/CentOS 6 & 7:

 

  1. Enable the dynamic CA configuration feature by running:

    sudo update-ca-trust enable

  2. Copy the CA certificate to the directory /etc/pki/ca-trust/source/anchors/:

    sudo cp rstudio-license.crt /etc/pki/ca-trust/source/anchors/

  3. Extract and add the CA certificate to the list of trusted CA's:

    update-ca-trust extract

 On Debian  / Ubuntu :

 

  1. Go to /usr/share/ca-certificates/ and create a new folder:

    sudo mkdir /usr/share/ca-certificates/rstudio

  2. Copy the CA certificate to the directory /usr/share/ca-certificates/rstudio:

    sudo cp rstudio-license.crt /usr/share/ca-certificates/rstudio/

  3. Ensure the permissions are 755 for the folder and 644 for the .crt file.  

  4. Then, Extract and add the CA certificate to the list of trusted CA's:

    sudo update-ca-trust extract
