==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

The CA certificates in the ca-certificates package were updated.

Software Description:
- ca-certificates: Common CA certificates

Details:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.10:
