Public bug reported:
DEP-8 tests of WireGuard are failing as of Ubuntu Questing, with
"/usr/bin/wg-quick: line 11: /usr/bin/readlink: Permission denied". It
only happens on architectures that are tested in VMs, and passes inside
the Questing armhf container, which indicates some kind of kernel issue.
VMs: testbed running kernel: Linux 6.16.0-13-generic
Container: testbed running kernel: Linux 6.8.0-58-generic
Another hint: The tests started failing after glibc/2.41-6ubuntu2.

Interestingly, I cannot seem to reproduce the issue locally in a QEMU VM, so
maybe it's an infrastructure issue:
$ autopkgtest -U wireguard --apt-pocket=proposed=src:wireguard -- qemu
/data/autopkgtest-questing-amd64.img
