Problem with libicu66 during installation php-intl extension on Ubuntu 21.10

All we need is an easy explanation of the problem, so here it is.

sudo apt install php7.0-intl


The following packages have unmet dependencies:
 php7.0-intl : Depends: libicu66 (>= 66.1-1~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Previous versions never had a problem with this dependency

Any ideas?..
