Unable to send bitcoin from bitcoin core wallet Using bitcoin core wallet fully synchronized with the blockchain on ubuntu



I click on "send".  Nothing seems to happen.
You are sending to a bech32 address. The current release of Bitcoin Core does not support bech32 addresses. The address box highlighted in read indicates that the address is invalid to the wallet.



The next release of Bitcoin Core will support sending to bech32 addresse as well as full Segwit wallet support.
