Re: Help With Command - sudo add-apt-repository ppa:bitcoin/bitcoin

If you only need to install Bitcoin Core, it's far easier to use ppa:luke-jr/bitcoincore (https://launchpad.net/~luke-jr/+archive/ubuntu/bitcoincore) which have newest version of Bitcoin Core.

Code:

sudo add-apt-repository ppa:luke-jr/bitcoincore
sudo apt update
sudo apt install bitcoinqt bitcoind
