Hi (and happy holidays!),

I am running flox 0.0.7-r106 and I tried to run `flox upgrade`:

```auto
floxmeta repository (/var/folders/kb/tjt27xcn6_dg095y88337mjm0000gn/T/tmp.IZDetxOz76/102) using deprecated (<=0.0.7) format.

Convert to latest (>=0.0.8) format?

           Yes No

```

then

```auto
error: Found argument '{}' which wasn't expected, or isn't valid in this context

Usage: nix-editor [OPTIONS] <FILE> <ATTRIBUTE>

```

What can I do to fix this?

Happy holidays!

There’s probably a bug in the conversion logic - could you `flox export > export.tar` and attach the result?

If you want to perform the conversion manually, you could inspect your old environment with `EDITOR=cat flox edit`, and then you could `flox destroy`, `flox edit`, and manually add all your packages (or `flox install` if you prefer). The new format should have entries of the form `packages.nixpkgs-flox.hello = {};`

</div>

How can I send you the tar file? It seems that I can not attach a file to a message here?

Just to be clear, the old format is:

```auto
[packages]
  [packages."bat"]
  channel = "nixpkgs-flox"
  stability = "stable"

```

and the new format should simply be:

```auto
  [packages."bat"]
  packages.nixpkgs-flox.hello = {};

```

?

</div>

For me there’s an upload button (icon has a little mountain)

`flox edit` should drop you into a template, but the new format will be

```auto
{...}: {
  packages.nixpkgs-flox.hello = {};
}

```

if you prefer you can nest multiple packages like:

```auto
{...}: {
  packages.nixpkgs-flox = {
    hello = {};
    jq = {};
  };
}
```

Stability and version can be added with:

```auto
{...}: {
  packages.nixpkgs-flox.hello = {
    stability = "unstable";
    version = "2.12";
  };
}

```

Happy holidays! In the reply-to box, the 7th icon should allow you to upload a file? If not, send it directly to me (I believe you already have my email address) and I’ll get it to Matthew. 🙂

It only seems to work for an image, not even a tar disguised as a jpg.

Do I understand that the whole file is a nix expression and not a toml file now?

Yes it is - documentation is pending. We may support TOML again at some point depending on how it’s received, but for now it’s just Nix

We have a quoting issue we hit for `ff="fzf --preview='bat {} --color=always'"`. Will ping once we’ve rolled out a fix!

Good to know. I was thinking that a simple fix would be to use the non pre-release of flox and remove that line with `EDITOR=vim flox edit` but this doesn’t seem to edit the file. Could you please tell me if there’s another way to edit it?

That approach worked for me - are you hitting some other error?

I guess it all depends on the flox version.

At the moment I have

```auto
○ flox --version default
Version: 0.0.7-r92

```

and

```auto
○ /usr/local/bin/flox --version default
Version: 0.0.7-r76

```

The first one tells me that `No environment changes detected .. exiting` after I edit and the second one failed with a few

```auto
       response body:

       {
         "message": "Not Found",
         "documentation_url": "https://docs.github.com/rest/commits/commits#get-a-commit"
# This is a prototype profile declarative manifest in TOML format,
       }; using cached version
warning: ignoring untrusted substituter 'https://cache.floxdev.com'
warning: error: unable to download 'https://api.github.com/repos/flox/nixpkgs-flox/commits/master': HTTP error 404

```

and now returns the same thing as the first one.

Maybe I should reinstall flox from the mac installer and then edit?

</div>

For me

```auto
> /usr/local/bin/flox --version
Version: 0.0.7-r84

```

so maybe installing would work.

Another workaround to try (not sure if it will work) would be adding or removing a package at the same time as the alias change to see if that avoids the `No environment changes detected` bug

Good idea. I tried to change a package during the editing and got:

```auto
remote: error: refusing to update checked out branch: refs/heads/x86_64-darwin.default
remote: error: By default, updating the current branch in a non-bare repository

remote: the work tree to HEAD.

error: failed to push some refs to '/Users/etorreborre/.cache/flox/meta/etorreborre'

```

Then I tried to add a new generation manually (I’m probably not supposed to do that :-)) and then try to edit with the most recent flox version. That led me to accept the 0.7.0 to 0.8.0 format migration but then I ended up having the same git issue above. Any idea on how to fix that one?

I’m a little lost about the failure, but you could try `flox git checkout floxmain` and then try again
