Since we generate the symlinks that are shipped by libdpdk-dev based on what libraries are actually built, rather than what packages are shipped, the symlink was present in libdpdk-dev and broken as correctly reported by Andreas' piuparts test, given the package with the actual library was amd64-only. PR is open to fix the error. -- Kind regards, Luca Boccassi
