The bug does reproduce for me on _some_ setups, all in regular sbuild: successful: amd64 FTBFS: armhf FTBFS: armhf qemu-user on amd64 successful: armhf on arm64
The timezone is the same, so is schroot/sbuild configuration, all what differs are architectures and kernel versions. And it's consistent for repeats. -- ⢀⣴⠾⠻⢶⣦⠀ Meow! ⣾⠁⢠⠒⠀⣿⡁ ⢿⡄⠘⠷⠚⠋⠀ Collisions shmolisions, let's see them find a collision or second ⠈⠳⣄⠀⠀⠀⠀ preimage for double rot13!
