Hi, I am on kubuntu 24.04 Noble with dotnet 7 installed from the ppa and the game works fine, even server.

Looking at what you posted above you could have residual .net 8 files or dependencies which interfer with the .net 7 installation. (dotnet-host-8.0 : Conflicts: dotnet-host). I would not deal with dependencies individually but let the dotnet8 and dotnet7 packages do their stuff, always safer that way.

At the top of this webpage they warn against this: https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu

What I would do is check the current .net installs: $ sudo apt list dotnet*

If you have both some .net 7 and .net 8 packages installed, hence the conflict, I would uninstall .net 7, re-install .net 8 to resolve conflicts, then proceed to remove .net 8 properly. It's a bit long-winded but let's hope it resolves your dependency issues: $ sudo apt remove dotnet7 $ sudo apt install dotnet8 Then $ sudo apt remove dotnet8

Add the ppa for dotnet 7, if not already installed: $ sudo add-apt-repository ppa:dotnet/backports

Check: $ sudo apt update $ sudo apt list dotnet*

Install .net 7: $ sudo apt install dotnet7

Hope it works for you. Don't hesitate to update the issue tracker if it works so the issue can be closed.

Hello @pingouyn :wave:

It works now ! Thank you :blush:

I think it can be useful to add this tutorial somewhere on how to install the donet7. So I do not close this issue for now
