Did you ever run "apt update && apt -y upgrade" on this machine? The error message tells you that the release signing key is outdated, so you should figure out whether the key - which is part of the package "debian-ports-archive-keyring" - is still up-to-date. If you have never updated the machine, the key may also have expired. Also, I wouldn't use pbuilder unless you know what you are doing. sbuild is the commonly used tool these days and is much easier to set up, so I wouldn't bother wasting time trying to set up pbuilder. With sbuild, you just need to make sure that you use the correct sources.list and the correct archive signing key as both are different for Debian release architecture and Debian Ports. If you don't want to use the wiki guide I linked in the other mail, you can also try the script sbuild-developer-setup [1] by Michael Stapelberg [1] although I don't know how usable the script is for Debian Ports as it doesn't seem to have an option to specify the archive signing key or the sources.list with a separate parameter. As with many of these guides or scripts, they are unfortunately made with Debian on amd64 in mind so they might not work as they should on other targets, especially in Debian Ports.
