How to safely replace Ondrej PHP with Ubunbu 22.04 original PHP repositories?

Question

I have this problem, and now I don't know how to safely replace Ondrej PHP with Ubuntu 22.04 original PHP repository?

I have PHP-FPM.

Answer 1

If the server can be offline for a little bit, the most effective way to accomplish this goal will be to:

0. Stop Apache

1. Uninstall PHP

2. Remove the Ondrej PPA

   ^{Note: It may be prudent to visually confirm your .list files in /etc/apt and /etc/apt/sources.list.d to ensure that nothing is pointing to the Ondrej PPA location.}

3. Re-Install PHP and the various additional packages that you require

4. Restart Apache
