Webapp problem on Ubuntu_16.04.

I install kopano webapp on Ubuntu_16.04.

I hit

Not Found: PHP mapi extension not found
If you have upgraded Kopano Core, please restart Apache

Kopano WebApp can’t start because of incompatible configuration.

Please correct above errors, a good start is by checking your ‘/etc/php/7.0/apache2/php.ini’ file.

You can disable this configuration check by editing the file ‘/usr/share/kopano-webapp/config.php’, but this is not recommended.

What is my wrong?

Hi @abu-sayeed

you did not install the php-mapi package, or did not include this php module in your php configuration.

I solve this problem.
I update and upgrade my OS. Then I reinstall all deb Package.
