When installed as a snap:
```
sudo snap install curl
```

`curl` will prepend the downloaded data with a text warning on STDOUT:
```
$ /snap/bin/curl -fSs fmarier.org

Caution: You are using the Snap version of curl.
Due to Snap's sandbox nature, this version has some limitations.
For example, it may not be able to access hidden folders in your home directory
or other restricted areas of the os.
This means you may encounter errors when using snap curl to download files.
For those case, you might want to use the native curl package.

To stop seeing this message, run the following command:
curl.snap-acked

which cannot be automatically suppressed by piping to a file.

If we can detect that somehow, it would be nice to error out early with a helpful error message as well as the fix, i.e. running:
```
curl.snap-acked
```

Start by reading install.sh and tracing how it invokes curl. Check how the script could identify the Snap-provided curl before downloading, then define the failure path around the warning and the suggested curl.snap-acked command. Done means the broken Snap version is detected early and the user receives a helpful remediation message.
