Can't change shell in EC2 server
I am trying to change the default shell on Ubuntu server 13.10 on Amazon's AWS (AMI ami-ad184ac4).
I've tried:
~$ chsh -s /bin/zsh
But got:
Password:
chsh: PAM: Authentication failure
I've tried obvious passwords (e.g. ubuntu
) but always got the same error message - chsh: PAM: Authentication failure
.
Any idea why can't I change the default shell?
Solution 1:
Oddly enough, using sudo
with the username was the answer:
$ sudo chsh ubuntu -s /bin/zsh
