@danmoseley @ericstj @carlossanlop runtime will have to take an arcade update, a llvm-project update, and Jacques' change next month, plus a fix to the publish stage invoked here:

runtime/eng/pipelines/official/jobs/prepare-signed-artifacts.yml

. The problem seems to be that you're trying to upload all blobs to blobArtifacts, but there are now .msi's with duplicate names. From @joeloff:

[7:52 PM] Jacques Eloff
it organizes builds by feature band for VS insertions, so MSIs can be duplicated in multiple folders. Copying them the same location won't work.

because in staging, each sets of files for each feature band is published to a separate VSDROP container and there can be overlap, but not all blobbies have the same files.

Wanted to make sure this was on your radar. The failure happens during the AzDO artifact upload task that happens at the end of that step:

Async Command Start: Upload Artifact
...
Fail to upload 'D:\a_work\1\s\artifacts\PackageDownload\IntermediateArtifacts\workloads-vs\Insertion\6.0.300\Microsoft.AOT.win-x64.Cross.android-arm.6.0.7.msi' due to 'Blob is incomplete (missing block). Blob: af95b7c0d1f1ec11b656501ac504b8de, Expected Offset: 0, Actual Offset: 4194304'.

Could someone with perms merge this? We need it to unblock the July 6.0 build

@joeloff @wtgodbe can one of you please file an issue with the details around what needs to be done to absorb the arcade breaking change here? Please be more specific than what's already been shared above - like what component in arcade changed, why it changed, and how we need to react in dotnet/runtime to absorb that. If this information has already been shared then please copy it into an issue in the repo and assign the right labels. Thanks!
