Users with default shell /bin/fish don't appear on login screen

[ckissane]

What Happened?

After changing my default shell to /bin/fish and logging out, the greeter thought there were no users and even took me to the user creation screen you see when first setting up the OS. After some shots in the dark I found that using a tty to change it back to bash let me log in again on the greeter.

Steps to Reproduce

1. apt install fish
2. sudo chsh USER_HERE -s /bin/fish
3. logout

Expected Behavior

They appear

OS Version

6.x (Odin)

Software Version

Latest release (I have run all updates)
