Problems with .NET 8 on build server (alpine amd64) with nuget path set

[inf9144]

Describe the bug
After upgrading to .NET 8 the build server is not able to compile our solution anymore.

/builds/X/X/.nuget/aspnetcore.sasscompiler/1.69.5/build/AspNetCore.SassCompiler.targets(11,5): error : Error running sass compiler: /builds/X/X/.nuget/aspnetcore.sasscompiler/1.69.5/build/../runtimes/linux-x64/sass: exec: line 20: /builds/X/X/.nuget/aspnetcore.sasscompiler/1.69.5/runtimes/linux-x64/src/dart: not found [/builds/X/X/XYZ/ABC/ABC/ABC.csproj]

To Reproduce
Use dotnet restore/run/build/test with --packages referencing a directory (relative path) like .nuget like:

dotnet restore --packages .nuget
dotnet build --no-restore
dotnet test --no-restore --no-build

Expected behavior
Would expect that dart is found and SassCompiler works as normal.

System
Container: mcr.microsoft.com/dotnet/sdk:8.0.100-1-alpine3.18-amd64

Additional context
In the local folder on my windows (with .nuget sitting in C:\user\XXX\.nuget) i can see the 'dart' file in the folder where the build script under linux says it's missing.

Hey,
Try add RUN apk add gcompat
before dotnet build

Thanks @czkawka for providing the solution, I've tested it myself and that works indeed.

I'll add this to the readme as well so it can easily be found in the future.
