# check the PHP version that we have running: root@server:/opt/web/mysite.com# php --version PHP 7.4.12 (cli) (built: Nov 3 2025 14:32:41) ( NTS )
Find your version.
And then:
# get what's missing for our PHP version: apt-get install php7.4-curl apt-get install php7.4-mbstring apt-get install php7.4-bcmath
