Rider 2024.2.7 - Error: Select project not found on Ubuntu 24.04

For some reason Rider is giving me an error “Error: Select project not found.” in the Debug-Launcher. Essentially I can't run any web sites for some reason.

When i create a new Blazor or .NET Razor app the launcher will work. Once I restart my laptop the launcher configurations say that they can't find the project. If I try to select a project or runtime there is nothing in the list. Any ideas?

Ubuntu 24.04.1 - with updates
Rider 2024.2.7 - with updates

I also tried to revert back to the latest stable 2023 version with the same results.

Hello Donniecrump,

This can happen if there is an issue with .NET installation paths/environment variables preventing Rider from accurately detecting valid .NET SDK installations.

Could you clarify how .NET SDK was installed on your system — using Ubuntu repositories, Microsoft repository, snap or manual installation method? 

If you used Microsoft repository to install/update .NET SDK, did you use Ubuntu repositories in the past to install .NET?

I installed it using the Ubuntu App Center. It is the latest stable 8.0.403 version published Oct 9th from Canonical. I'm not sure how I installed it previously, but I can try to perform a manual install to see if that helps.

Donniecrump, 

Thank you for the information. It sounds like .NET SDK was installed as a snap and there might be an issue with environment variables.

Could you execute the following few commands in the terminal and attach the output of each of them?

snap list
dotnet --info
which dotnet
echo $DOTNET_ROOT

Note that you can also save the output of these commands in a file and share it with us via the Upload Service if you are more comfortable sharing this information privately.

I install the SDK from apt-get and verified the dotnet --version 8.0.110. I then checked the settings to make sure Rider was finding the correct path to the SDK. All of this looks good but I'm still unable to run my web site. The interesting thing is i can build the project but not run it. It can't seem to find my project to run. I only have one project in my “solution” so it shouldn't be a conflict issue.

Also, if I try to delete the current configurations and create new ones there are no projects listed to choose from.

Donniecrump, .NET SDK 8.0.110 is a slightly older version of .NET 8 installed from ubuntu repositories. This version of .NET uses non-standard install locations.

 

You'll need to set DOTNET_ROOT pointing to your current .NET install location (/usr/lib/dotnet). Please try the following steps in your environment:

  • temporarily set DOTNET_ROOT in the terminal (DOTNET_ROOT=/usr/lib/dotnet) 
  • run Rider in the same terminal using CLI. Command-line interface describes how you can start Rider using CLI, depending on the installation method. You can also use snap run rider if you installed Rider with snap.

I ran rider after setting the DOT_NET path and running from the rider launcher file here is what it read out. Also .. at first I had install Rider via the Ubuntu App Store, currently I have it installed using the Jetbrains Toolbox.

Donniecrump, thank you for the information. This should not affect how Rider runs your project. 

 

Could you check if you are able to run your project when you run Rider via CLI after setting DOTNET_ROOT?

Still the same issue with launcher. Here is the output from the command line. It looks a little different when I opened my project.

Donniecrump,

Regrettably, I was not able to reproduce this issue in a testing environment. 

Could you reproduce this issue again (try to run the project in Rider) and send us your Rider logs via the Upload Service? Please leave a comment with Upload ID in this thread.
