I've followed this tutorial to install php7.4 on Ubuntu 22.10.

As far as I know, I just need to add this PPA and update my repositories with

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update

and then install php7.4 with

sudo apt-get instal php7.4

However, I'm getting this error:

nugroho@vostro:~$ sudo apt-get update

Package php7.4 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or

E: Package 'php7.4' has no installation candidate

Is php7.4 not yet supported on Ubuntu 22.10, or did I make a mistake?

Below are some details about my install:

No LSB modules are available.

I've followed the steps below and it worked out fine! (thanks to Item-alert reddit link)

i had the same problem after upgrading from 22.04 to 22.10 and php 5.6.(in my case php 7.4) I solved it by changing /etc/apt/sources.list.d/ondrej-ubuntu-php-kinetic.list.

deb https://ppa.launchpadcontent.net/ondrej/php/ubuntu/ jammy main
#deb-src https://ppa.launchpadcontent.net/ondrej/php/ubuntu/kinetic main

Of course, run the apt update command

There are a couple of elements at work here.

First, the PHP version follows Ubuntu by default. So any installation of PHP other than 8 on Ubuntu 22.10 is non-default.

One method is using the ppa:ondrej/php. However, the PPA needs to be updated for each distribution, which hasn't happened yet for 22.10.

Another option is to install PHP (and possibly Apache etc.) using containers. In this case, the PHP version can be independent from the system.

Any other manual installation of a non-default PHP version is not recommended, since it can cause package dependency issues in the long run.

I solved the same problem by downloading and installing manually (using dpkg install) the libicu70 library from the Ubuntu packages https://packages.ubuntu.com/jammy/amd64/libicu70/download

Then sudo apt install php7.4-intl goes smoothly.

EDIT The dependency issue only appeared after the first step that I forgot to mention : using jammy instead of kinetic in ppa:ondrej/php as kinetic is not yet available from that PPA. (Note that this whole answer has a very short life expectancy.)

php-fpm 7.4 via Docker method

You may wish to consider installing PHP 7.4 in a Docker container, while Apache runs in the host system.

I posted a full guide on Stack Overflow to cover the general (version-independent) steps necessary, but in this post I will focus on the specific considerations of using PHP 7.4 on Ubuntu 22.10 -- especially now that PHP considers 7.4 to be past end of life.

Rationale

I decided to go this route as I don't think the usual ppa:ondrej/php PPA will be updated to include 7.4. Per their website, "Only Supported Versions of PHP . . . Don't ask for end-of-life PHP versions." PHP 7.4 is now EOL, so we should not expect this PPA to be added.

Additionally, as others have mentioned in this thread already, mixing PPAs designed for different releases may result in future dependency errors.

Consideration: Updates

The official PHP 7.4 Docker image is no longer updated (based on the github for it), so don't use the php:7.4-fpm image in production (or any internet-facing usage) as-is. It should be reasonably safe in a localhost development environment, though.

Note -- Debian / Ubuntu will continue to receive PHP 7.4 updates for some time, even after PHP has already declared it EOL. It should be possible to set up a docker container based on Debian/Ubuntu's 7.4 php-fpm which should still be supported until 20.04 reaches EOL. There are 1,515 results for PHP7.4 on dockerhub, so there's a good chance someone is already doing this.

Also, if you go this route because you intend to deploy to production, you will also likely want to investigate automated build methods to keep the container updated. Though it's generally non-advisable to deploy a production web server on a non-LTS release.

Consideration: Tuning

It should also be noted that tuning settings or adding future plugins is cumbersome because it requires a full docker rebuild instead of just editing a config file or running a single apt command.

A possible workaround is that you could share the php-fpm config on a virtual host folder.

Next steps

Follow the main guide here for general instructions. Instead of using the official php:7.4-fpm package, you may wish to explore non-official images to mitigate the EOL issue.
