Challenge

Veeam Agent for Linux connecting to a Cloud Repository with a seemingly valid Cloud certificate fails with "certificate has expired".
kb4015_1

Cause

On May 30th of 2020, Sectigo had an expired Root CA that will not be updated due to the age of the certificate. https://support.sectigo.com/Com_KnowledgeDetailPage?Id=kA03l00000117LT

 

 

Solution

To resolve this issue, the following steps must be performed:

  1. Change directory to the certificate location: cd /etc/ssl/certs
     a. Check for AddTrust_External_Root.pem: ls
kb4015_2

    b. If present, remove it with: sudo rm AddTrust_External_Root.pem

2. Next, change the directory to the configuration file for global certificates: cd /etc

         a. Edit the configuration file: sudo nano ca-certificates.conf or sudo vi ca-certificates.conf
         b. Look for mozilla/AddTrust_External_Root.crt and comment it out:

kb4015_3

3. Next, update the global cache by running: sudo update-ca-certificates

You will then be able to reconnect to the cloud repository.
