I'm trying to push my dot files and some personal configuration files to a server (I'm not root or sudoer). Ansible connects as my user in order to edit files in my home folder.

I'd like to set my default shell to usr/bin/fish. I am not allowed to edit /etc/passwd so

user:
  name: shaka
  shell: /usr/bin/fish

won't run.

I also checked the chsh command but the executable prompt for my password.

How could I change my shell on such machines ? (Debian 8, Ubuntu 16, Opensuse)
