我在 Debian 上运行 PHP 7.4.6，想要升级到 7.4.12 我运行此命令
sudo apt-get --only-upgrade install php7.4
我明白了

E: Unable to locate package php7.4
E: Couldn't find any package by glob 'php7.4'
E: Couldn't find any package by regex 'php7.4'
所以我尝试了这个
sudo apt-add-repository ppa:ondrej/php
计划在之后运行这些命令
sudo apt-get update
sudo apt-get install php7.4
但是一旦我运行sudo apt-add-repository ppa:ondrej/php并按下回车键我就得到了

如何修复此问题以在 Debian 10 上将 PHP 7.4.6 升级到 7.4.12？
