I have been following the What is the fastest way to synchronize the daemon? post to import the blockchain.
I download the blockchain.raw successfully but I got error at importing the last block:

I tried using the --dangerous-unverified-import 0 and --dangerous-unverified-import 1 options with no vain. I also think that the downloaded blockchain is complete, see the wget output:
$ wget -c --progress=bar https://downloads.getmonero.org/blockchain.raw

The file is already fully retrieved; nothing to do.
Could someone kindly help me to resolve the importing problem?
EDIT:
For more information, I tried the mb_stat command to check the inconsistencies in the blocks:
$ mdb_stat -ea ~/.bitmonero/lmdb/

However, I am not sure how to verify if the blocks are consistent or not.
