How to upgrade WordPress(one clink) php 7.4.1

I'm assuming you use Ubuntu 20.04 or Debian 10. If that's not your distro of choice then keep looking elsewhere for the answer.

• For PHP, see here:

Note that PHP 7.4 is not supported on Ubuntu 20.04 or Debian 10.

• For Wordpress, see here:

https://wordpress.org/support/article/updating-wordpress/

Please note, that doing this has the potential to break every single plugin you use, your Wordpress installation in general and any other thing you have that depends on PHP. Fixing all that is your responsibility. You've been warned…

Backups are your friend.

20.04 (Focal Fossa) does indeed carry PHP 7.4 by default. 7.4.3 is the version currently in focal-updates.

You’re right about Debian 10 - it’s only carrying 7.3 in Buster.
