Not sure I understand why the linux build is failing...

Can you try that? Just swapping the directories. I don't know how it works but it's the only thing that seems affecting the process and not being backward compatible.

edit: except if you really need that match first with snap, in that case my changes are useless.

Also you check this out?

@ziggy42 I don't believe it's related to the PR. I'll investigate this when I have a spare moment.

@LuKks the order of these paths should only matter if you have both installed. Something needs to be chosen, and a pattern that's good to go with here is something like:

• when multiple versions are found, favour the latest version
• when multiple installations found of the same version, favour the one that's more specific to the user

I don't have strong feelings on what order we should use here, just that we choose something and try to stick to it...
