    Ubuntu Security Notice USN-4377-1
    June 01, 2020
    
    ca-certificates update
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 20.04 LTS
    - Ubuntu 19.10
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    An expired certificate was removed from ca-certificates.
    
    Software Description:
    - ca-certificates: Common CA certificates
    
    Details:
    
    The ca-certificates package contained an expired CA certificate that caused
    connectivity issues. This update removes the "AddTrust External Root" CA.
    
    In addition, on Ubuntu 16.04 LTS and Ubuntu 18.04 LTS, this update
    refreshes the included certificates to those contained in the 20190110
    package.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 20.04 LTS:
      ca-certificates                 20190110ubuntu1.1
    
    Ubuntu 19.10:
      ca-certificates                 20190110ubuntu0.19.10.1
    
    Ubuntu 18.04 LTS:
      ca-certificates                 20190110~18.04.1
    
    Ubuntu 16.04 LTS:
      ca-certificates                 20190110~16.04.1
    
    In general, a standard system update will make all the necessary changes.
