Description

The instructions for installing the trusted root certificate for Fiddler Everywhere on Linux utilize the Debian dkpg-reconfigure command. However, some Linux distributions like Fedora, CentOS, and RedHat might lack the dkpg library or limit its usage. How can I install and trust the Fiddler root certificate while using the update-ca-trust command?

Solution

  1. Install and open the Fiddler Everywhere application on a shared system certificate storage Linux distribution such as Fedora, CentOS, or RedHat.

  2. Export the Fiddler Everywhere root certificate through Settings > HTTPS > Advanced Settings > Export Root Certificate to Desktop.

  3. Open a terminal and copy the exported certificate to the shared certificate storage. The following example uses the default paths on Fedora 33.

    cp ~/Desktop/FiddlerRootCertificate /etc/pki/ca-trust/source/anchors/
    
  4. Trust the certificate by updating the certificate authority through the following terminal command:

    update-ca-trust
    
  5. Return to Fiddler Everywhere and enable the HTTPS capturing by selecting the Settings > HTTPS > Capture HTTPS traffic checkbox.
