The following packages have unmet dependencies:
php5-json : Depends: phpapi-20121212
E: Unable to correct problems, you have held broken packages.

How can I fix this problem?

Solution 1

It looks like you are install PHP5 from a custom repo. I would remove PHP and remove that repo.

sudo apt-add-repository --remove ppa:ondrej/php5-5.6
sudo apt-get update

now install php

sudo apt-get install php5-common php5-json

Solution 2

Below solution worked for me-

cd /etc/php5/mods-available
vi json.ini

In this file make below changes

priority=20
extension=json.so

Incase if json.ini file is not there, create the file with contents as

priority=20
extension=json.so
