Move from Ubuntu 14.04 to 18.04 AND php7 upgrade error vs. 4.8.4

[scdzaak]

On the Ubuntu server 14.04 I got the error in ECRM that the PHP version was not supported.
Fine so far.

I made new server on Ubuntu 18.04 LTS with PHP 7.2.x
I migrate the ECRM and MySQL database to the new server.
The application is working fine .. no error and I can use ECRM as before.

Now I want to upgrade to the latest versions .. first from 4.8.4 to 5.0.5 .. but I get the error:
Your PHP version does not support this installation package .. weird ..

Will I miss something .. on the new server..
Regards,
Eric

maybe you didn't install zip extension for php or it failed after upgrade

@ Tanya,

That was the trick .. I had updated the next files to the latest ones:

apt-get install php-pear php-fpm php-dev php-zip php-curl php-xmlrpc php-gd php-mysql php-mbstring php-xml libapache2-mod-php
