    Remove the Ethereum repository first:

    sudo add-apt-repository --remove ppa:ethereum/ethereum
sudo apt update

    Remove imported GPG key:

    sudo apt-key del 2A518C819BE37D2C2031944D1C52189C923F6CA9

    Import GPG key of the Ethereum repo again:

    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 2A518C819BE37D2C2031944D1C52189C923F6CA9

    Add repository again:

    sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt update

    UPDATE

    Remove the Ethereum repository again:

    and next

    gpg --export --armor 2a518c819be37d2c2031944d1c52189c923f6ca9 | sudo apt-key add -

    Add repository for Ubuntu 16.04:

    echo -e "deb http://ppa.launchpad.net/ethereum/ethereum/ubuntu xenial main" | sudo tee /etc/apt/sources.list.d/ethereum-ubuntu-ethereum-xenial.list

    Update apt:

    sudo apt update

    Install software you want from the Ethereum repository.
