@vansangpfiev is this what we expect for this issue?

• Y Doesnt hang
• But errors something went wrong cannot copy file (this shouldnt be triggered)

[vansangpfiev]

@gabrielle-ong It is expected, because the download binary does not exist.
However, it can be improved, we should not try to update binary if download failed.

Update: the download binary does exist but it is empty, so the logic is correct in this case.
