I installed the flox deb on Ubuntu 22.04. My default shell is fish (3.3.1).

Steps to reproduce:

- cd $HOME
- flox init
- flox activate

What should happen:

```auto
✅ You are now using the environment 'default'.

```

What happens instead:

```auto
✅ You are now using the environment 'default'.
To stop using this environment, type 'exit'

~/.flox/run/x86_64-linux.default/activate.d/fish (line 17): 'return' outside of function definition
  return 1
  ^
from sourcing file ~/.flox/run/x86_64-linux.default/activate.d/fish
source: Error while reading file “/home/user/.flox/run/x86_64-linux.default/activate.d/fish”

```

This happens every time I try to activate the environment.

[Apparently I can!](https://launchpad.net/~fish-shell/+archive/ubuntu/release-3) I will give that a go and report back.

Confirmed that with fish 3.7.1 as my default system shell, I can now `flox init; flox activate` without error!

So great to hear!

We’re working on fixing the support for older versions as well! [Flox failing when using fish shell · Issue #2016 · flox/flox · GitHub](https://github.com/flox/flox/issues/2016)
