Fixes #3505

  • .NET 9.0 was released on November 12, 2024, which fixes the underlying issue with the armv7l breakage on newer ubuntu containers due to arm32 Y2038 compatibility issues with the underlying Ubuntu/Debian operating systems moving to 64-bit time.
  • These fixes are in .NET 9.0, but will not be backported to .NET 8.0 as per Breaking change: .NET 9 is Y2038 compatible (Arm32 glibc); .NET 8 is not dotnet/core#9285
  • I also updated the builds to use ubuntu/noble (LTS) since .NET 9.0 doesn't appear to be supported on the older ubuntu jammy containers.

Updating .NET to version 9 is necessary to keep supporting armv7 as .NET won't fix the incompatibilty in version 8.

I assume we will lose the support for ubuntu 20.04 or debian 11 for arm32?

users of these versions might have to install .NET 9.0 from the Microsoft repository.
But they migt need a higher glibc version also.

I will check if thats reasonable

Basically, the dotnet 8 runner should work on ubuntu 22.04 or below, just not ubuntu 24.04 or above is what my understand.

That is also my understanding. The newer breakage is only with 32-bit runners. (We don't have this issue with our x86 32-bit runner because we run that inside a x86_64 based container...)
