This is due to disappearance of s390x and ppc64le arches in [repos](http://httpredir.debian.org/debian/dists/buster/main/) of `buster` (currently used Debian). Not sure why arches disappeared, but turns out that `buster` soon reaches end of LTS support ([2024-06-30](https://wiki.debian.org/LTS)).

In newer JDKs, sysroot update to bullseye was included in [JDK-8293107](https://bugs.openjdk.org/browse/JDK-8293107) (GHA: Bump to Ubuntu 22.04). I have tried Ubuntu update in GHA as well, but it failed to build on some platforms (aarch64, ppc64le)  with errors such as:
