I've been scratching my head over this regression [1] for a while now, in the context of running a hirsute container on a 20.04 host (in particular, a GitHub workflow machine) In my case, the symptom is that after upgrading glibc, `which` is broken; that of course also uses faccessat(), similar to test -x.
I tried all sorts of the "usual" workarounds, as seccomp has been giving trouble for a while now [2]. But this failure is robust against fuse- overlayfs vs. vfs (inefficient full copies of the file system), root vs. user podman, podman vs. docker, and, relevant for this bug, it *also happens* with --security-opt=seccomp=unconfined and/org --privileged, both of which should disable seccomp. Hence I believe this bug can't at least only be in libseccomp.

From comparison this seems to be caused by apt 2.1.20. The build fails with: 0E: gnupg, gnupg2 and unupg1 do not seem to be installed, but one of them is required for this operation The simple Dockerfile to reproduce the error - "docker build -t foo ."

Running this manually works only in an --privileged container. So adding keys in unpriviledged container or possibly kubernetes will not work anymore.
