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


On May 30th of 2020, Sectigo had an expired Root CA that will not be updated due to the age of the certificate.




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

    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:


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

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


See RedHat KB article 5117881.


Install SUSE-RU-2020:2428-1 for SLES12 or SUSE-RU-2020:2284-1 for SLES15; alternatively, upgrade ca-certificates-mozilla to version 2.42 or later.
