If the checksum you provide doesn't match the checksum of the remote file, 
then I don't think it will download anything.  If the checksums do match and 
you don't have a local copy of the file, then there should be multiple 
download attempts.

The checksum is compared against the remote file, not the local one.

IIUC, checksum is always sha256.  If you use anything else, you are likely to 
be unpleasantly surprised.
