Upgraded to 18.04 from 16.04 today using do-release-upgrade -d
During the upgrade I was informed that some packages would be removed, these included:
Remove: libperl5.22 lxc-common perl-modules-5.22 php-imagick
php7.1-curl php7.2-curl python3-certbot-nginx
I could re-install imagick and certbot without issue, but if I try to install php7.2-curl I get the message:
# apt install php7.2-curl -y
Reading package lists... 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:
php7.2-curl : Depends: php7.2-common (= 7.2.3-1ubuntu1) but 7.2.4-1+ubuntu16.04.1+deb.sury.org+1 is to be installed
E: Unable to correct problems, you have held broken packages.
How can I correct the situation?
回答1:
This can save you:
sudo add-apt-repository ppa:ondrej/php
sudo apt update
sudo apt install php7.2-fpm php7.2-gd php7.2-curl php7.2-mysql php7.2-dev php7.2-cli php7.2-common php7.2-mbstring php7.2-intl php7.2-zip php7.2-bcmath
Then sudo service apache2 restart

You don't need to add a new repo. Just do this and the 7.2 version will be installed. Remember to restart php and apache after. Also make sure (you've prob already done this though) to enable the new mod after:
sudo apt install php-curl
sudo a2enmod php7.2
You'll also notice probably that at the end of the install of php-curl (which installs php-curl and php7.2-curl) the following (Note that I have FPM setup, might look different if you're not using FPM):
NOTICE: Not enabling PHP 7.2 FPM by default.
NOTICE: To enable PHP 7.2 FPM in Apache2 do:
NOTICE: a2enmod proxy_fcgi setenvif
NOTICE: a2enconf php7.2-fpm
NOTICE: You are seeing this message because you have apache2 package installed.
So do what it says:
sudo a2enmod proxy_fcgi setenvif
sudo a2enconf php7.2-fpm
sudo systemctl restart apache2.service

Installing libcurl4 worked for me using
apt install libcurl4
Then installed php7.2-curl, restarted apache2 without an issue.
