Bug#2259: popclient: clearbiffbit: fchmod: Operation not permitted
It's saying it can't change the mode of a terminal device. "biff", a
primitive mail notification program named after Heidi Stettner's dog,
uses one of the unused mode bits of the device to tell whether it
should write messages to your terminal or not.
