Can we if-Condition to only run on supported platforms / not run on non-supported platforms (linux-musl-x64 and linux-musl-arm64)?
Maybe by splitting it into a step that does sudo rm, and another step that does the sudo apt-get (but not for Alpine Linux)?

Maybe something like:

- name: Remove unused packages
  if: ${{ !contains(matrix.container.image, 'alpine') }}
  run: |
    # Clean up apt packages
    sudo apt-get ...
    ...

That's pretty much what we had before:

I'll put that bit back since the freediskspace action is ineffective on the containers.

Oh, I meant to just execute thesudo apt-get conditionally, since they produce the ::warning:: messages.
But keep the sudo rm on all Linux runners, since they seem to work just fine.

Ah OK, we can tidy up the non-container runners in another PR if need be 👍🏻

Bug: Cleanup action runs inside container, not on runner

The condition if: ${{ !matrix.container }} was removed from the "Remove unused applications" step. This causes the freediskspace action to run inside Alpine containers rather than being skipped. Since the PR aims to free space on the runner (not the container), running cleanup inside the container won't achieve the intended goal. Additionally, the freediskspace action uses Ubuntu-specific commands (apt-get) that don't exist in Alpine Linux (which uses apk). The original condition correctly prevented this action from running when a container is specified.

# Remove build binlog (can be large, often 100MB+)
rm -f build.binlog || true

# Clean up NuGet HTTP cache (not the packages cache which is needed for pack)
dotnet nuget locals http-cache --clear || true

echo "Disk usage after cleanup:"
