It looks like that powerpc chroot is not up-to-date, as it is installing dpkg 1.22.6, where the change to pass -Wno-error was done in dpkg 1.22.7. From the log: Toolchain package versions: binutils_2.42.50.20240710-1 dpkg-dev_1.22.6 I guess this needs to be either reassigned to some porter pseudo-package or missing that, then closed and the porters contacted separately. Feel free to do whatever might be appropriate here. :) Thanks, Guillem
