Can’t install php7.2-ldap on Ubuntu 18.10 – “unmet dependencies”

Recently I’m working with Laravel and LDAP (Active directory) authentication. But I can’t install php7.2-ldap, I also tried to install in php7.3 but failed.

Currently I’m using ubuntu v18.10 with multiple php version.

I tried: $ sudo apt-get install php7.2-ldap and got this output

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php7.2-ldap : Depends: php7.2-common (= 7.2.19-0ubuntu0.18.10.1) but 7.2.20-1+ubuntu18.10.1+deb.sury.org+1 is to be installed
E: Unable to correct problems, you have held broken packages.

I also tried $ sudo apt-get update and upgrade also before do it.

Answer

7.2.20-1+ubuntu18.10.1+deb.sury.org+1 is to be installed

deb.sury.org refers to Ondřej Surý PPA, you need to reinstall php following these steps :

• You need to have the software-properties-common package installed :

  sudo apt-get install software-properties-common
  

• Add the ondrej PPA repo and update sources :

  sudo add-apt-repository -y ppa:ondrej/php
  sudo apt-get update
  

• Install php and needed extensions :

  sudo apt-get install php7.2-common php7.2-ldap
