Password: After some hours of debugging there seem to be two ways to make it upgrade: 1. use usermod instead of chsh in libuuid1's postinst script 2. change chsh's PAM configuration to not include "auth required pam_shells.so". Since I'm not a PAM expert by any means, I cannot say anything about 2. The first appraoch is implemented by the attached patch. If you think this is a bug in chsh instead, please reassign accordingly. Cheers -- Sebastian Ramacher
