Why can't I install php7.4-intl on Ubuntu 20.04?

  • 772

I need the INTL module for PHP on Ubuntu 20.04. When I do

$ sudo apt install php7.4-intl

I get

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php7.4-intl : Depends: php7.4-common (= 7.4.3-4ubuntu2.2) but 7.4.8-1+ubuntu19.10.1+deb.sury.org+3 is to be installed
E: Unable to correct problems, you have held broken packages.

We all know that the broken packages message is a red herring. (Yes, I checked...)

As I'm on 20.04 I'm supicious against the ubuntu19.10.1 part of the package that apt suggests.

PHP says:

PHP 7.4.8 (cli) (built: Jul 13 2020 16:46:06) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.8, Copyright (c), by Zend Technologies

which makes me even more confused. I have tried what I can find googling to remedy any inconsistencies in the apt configuration and cache. (dpkg --configure -a, apt clean/autoclean, ...)

dependencies apt php7

    php7.4-intl is being installed from the Ubuntu repositories, not the deb.sury PPA / third party repositories you have installed and are using for your PHP.

    Either don't install php-intl or don't use the deb.sury repos. The use of the third party repositories is going to inhibit you from installing everything if it isn't provided in those third party repositories.
