Since you are “bob” in this exercise, just do chsh directly, and you will not see the PAM error:

bob@caleston-lp10:~$ grep bob /etc/passwd
bob:x:1000:1000::/home/bob:/bin/bash
bob@caleston-lp10:~$ chsh -s /bin/sh
Password: 
bob@caleston-lp10:~$ grep bob /etc/passwd
bob:x:1000:1000::/home/bob:/bin/sh
bob@caleston-lp10:~$
