Drush PM-Update fails with “File views.7.x-3.x-dev.tar.gz is corrupt (wrong MD5 checksum)”!

I get this:

Code updates will be made to the following projects: Views [views-7.x-3.x-dev]

Note: A backup of your project will be stored to backups directory if it is not managed by a supported version control system.
Note: If you have made any modifications to any file that belongs to one of these projects, you will have to migrate those modifications after updating.
Do you really want to continue with the update process? (y/n): y
