I was trying to install a package using APT and I got error:

How can I fix this?

This commands helps me:

1) Remove PHP and all his libraries and files

sudo apt-get purge php7.*

2) Install PHP again

sudo apt-get install php7.2

It seems there's a bug in the php7.1 for the Ubuntu distribution: https://bugs.launchpad.net/ubuntu/+source/php7.1/+bug/1710007

The issue can be fixed running the following commands before installing "libapache2-mod-php7.1":

sudo apt-get remove --purge php* -y && apt-get purge libapache2-mod-php* -y
