My two cents here: You are using an APT mirror of your cloud provider (which is nice and speed things up), but it appears that it has some issues with the mirrored files. Related discussion:
You could try to use a different APT mirror instead and check whether the issue goes away, you can switch back to the original mirror when the issue has been resolved.
