Not detecting a certain type of .NET Linux installation

[Fern-Leaves]

Please confirm the following

• I am using the latest stable/beta version of Fuji
• I have confirmed that this issue is not caused by a faulty mod
• I have searched and confirmed that this issue is not a duplicate

What were you doing?

I was trying to install fuji on my steam deck, I got the Linux x64 version, the installation tutorial told me I need to install .NET and to follow Microsoft's tutorial for doing that on Linux, I tried the installation script method, fuji still says .NET isn't installed, I tried installing it with pacman (not recommended on steam deck as pacman installed packages will be cleared with updates to steamos), fuji still says .NET isn't installed

Your logs

there are no logs to speak of as this issues comes before Fuji even opens but I can provide exactly what it says when I tell Fuji to "run in konsole", and yes I have tried what it tells me to do but that link just leads me back around to the link Fuji tells me about on how to install .NET on Linux, which I have followed:

You need .net 8 or higher, it seems like you installed .net 7.
dotnet-runtime on the arch repos will do the trick.

I'm going to assume this is resolved now with Wartori's comment. If it isn't, feel free to reopen.

I literally did install dotnet through pacman with the dotnet-runtime thing, and it will say there it is the version I need, fuji just doesn't detect it.

[Wartori54]

Really make sure that the version installed is .NET 8.x.x, you can verify so with dotnet --list-runtimes and also verify that it is on the standard location (/usr/share/dotnet/shared/).
Verify that DOTNET_ROOT is not set when you are running the app as well.
And if pacman does not want to install the correct version (maybe because of steam deck shenanigans) try the "official standalone installation", documented here.

iirc that I found a solution to this, I don't remember it right now and am not at my main computer

[Wartori54]

Your issue here is that the mac apphost targets 8.0.6, and 8.0.4 is installed instead, leading to no match.
Maybe the fuji team could downgrade the runtime requeriments in order to not be as high (maybe target base 8.0.0 instead).
