    I ran into the same problem to some extent and for some reason ppa:ondrej/php didn't work on Ubuntu 18.04. As mentioned in this article, after adding the following repository, I successfully installed php7.4

    sudo add-apt-repository ppa:sergey-dryabzhinsky/php74
sudo add-apt-repository ppa:sergey-dryabzhinsky/php7-modules
sudo add-apt-repository ppa:sergey-dryabzhinsky/backports
sudo add-apt-repository ppa:sergey-dryabzhinsky/packages
