Adding and trusting a Certificate Authority (CA) in Fedora
When running Citrix on Fedora, I was getting an error message similar to the following: “SSL Error 61: You have not chosen to trust ‘Certificate Authority’”. Basically, the CA (certificate authority) cert was missing in my operating system. To fix this, we need to do the following:
- Find the CA’s certificate online.
- Ensure that the certificate is in PEM format (if not, convert it to PEM).
- Move the PEM file to
/etc/pki/ca-trust/source/anchors. - Update the CA trust in the operating system.
In the example below, I add and trust GoDaddy’s root G2 certificate:
# Download GoDaddy - G2 root certificate
wget https://ssl-ccp.godaddy.com/repository/gdroot-g2.crt
# Convert CRT to PEM
openssl x509 -in gdroot-g2.crt -out gdroot-g2.pem -outform PEM
# Move the PEM cert and update the CA trust
sudo mv gdroot-g2.pem /etc/pki/ca-trust/source/anchors/
sudo update-ca-trust
