Description
I am just testing to create a Debian package for 4.3RC1. I get the following error:

=============================== warnings summary ===============================
I do not use the wcslib that comes with Astropy, but the Debian package, which is currently (we are in a freeze) older (7.4) than the one provided with Astropy. Therefore I guess these errors are probably temporary until we upgrade after the release of Debian Bullseye. I would recommend to ignore this; the report here is more for completeness.
Also, the error is simple to avoid by adding
