Dotnet Sonarscanner tool does not find .NET runtime

SonarQube Server / Community Build

SonarQube Community Build version: v25.3.0.104237
.NET sonarscanner tool version: 10.1.1
Deployment type: Docker

I am trying to get the dotnet scanner tool working on Linux. I have .NET 8 installed on the machine. Manually running dotnet build works fine.

But trying to start the scan via dotnet sonarscanner begin ... results in the following:

You must install .NET to run this application.

App: /root/.dotnet/tools/dotnet-sonarscanner

App host version: 8.0.14

Download the .NET runtime:
https://aka.ms/dotnet-core-applaunch?missing_runtime=true&arch=x64&rid=linux-x64&os=ubuntu.22.04&apphost_version=8.0.14

But running dotnet --info yields:

Finally, both .dotnet and .dotnet/tools are part of PATH:

# echo $PATH
/opt/java/openjdk/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/root/.dotnet:/root/.dotnet/tools

Silly mistake on my part, but I will provide the solution just in case anyone else stumbles upon the same issue. The problem in my case was that I am installing dotnet via the scripted install provided by Microsoft (Install .NET on Linux without using a package manager - .NET) and I forgot to also set the DOTNET_ROOT environment variable.

Once I set this variable as well, scanning works fine.
