Hey @dimas , Ah, that makes sense. Looking at the manifest files, they have the same Identity@Id (which is what ProGet uses for the Package Name) but a different Identity@TargetPlatform (which must be new-ish): <Identity Language="en-US" Id="python" Version="2025.2.0" Publisher="ms-python" TargetPlatform="win32-x64"/> <Identity Language="en-US" Id="python" Version="2025.2.0" Publisher="ms-python" TargetPlatform="linux-x64"/> We could probably figure something out in ProGet, but it's not trivial when it comes time to changing how we identify Package Names. Can you try editing the manfiest file inside the vsix archive, and seeing if that works for your use case? So basically: <Identity Language="en-US" Id="python-win32-x64" Version="2025.2.0" Publisher="ms-python" TargetPlatform="win32-x64"/> <Identity Language="en-US" Id="python-linux-x64" Version="2025.2.0" Publisher="ms-python" TargetPlatform="linux-x64"/> Not quite sure if that would work, but figure it's worth a try. Thanks, Alex
