While trying to build an image of librecmc both the from latest git clone, and from release v1.5.13-20230413 it fails at downloading ca-certificates from a few mirrors on which those certificates seem to no longer exist. That includes librecmc.org which, when checking manually, returns me to a 404.html page, that looks _identical_ to the home page.
