After upgrading to 2.4.3_1, package manager fails with "pkg-static: No trusted certificates"

The full text of the error, which occurs when trying to install or upgrade any package, is as follows:

Any ideas what may have happened or how to resolve?

What version were you running before the upgrade?
Can you post the contnet from /conf/upgrade_log.latest.txt?
