After pointing /boot/{initrd.img,vmlinuz} back to 6.2.0-27 and rebooting the software-updater wanted to remove the 6.2.0-31 kernel (done) and I catched the above log. Indeed the /lib/modules/6.2.0-32-generic/build symlink and hence the ~/scripts/sign-file is missing. And indeed the linux-headers-6.2.0-32-generic package is missing. As recommended I installed that package, which resolved the problem. :D
