Can someone explain me a bit how is it possible a block to have only 1 transaction

https://blockchain.info/block/000000000000000003c8190a9acbf9646dc81d121cb2b13fcc87b81281fd1838

And the fees are 0 BTC, i haven't seen before a block containing only a single transaction.

It just means that the miner mined a block that only has the coinbase transaction. This is allowed. They happen semi-frequently now but less so than in the past since there are more transactions to add. There are zero fees since the coinbase transaction has no fee with it and there are no other transactions to provide a fee.

Does it mean that at that time there was no unconfirmed transaction.

Or it was manually pushed to get only the mandatory transaction?
