[Vtigercrm-developers] Install 7.0.1 on Ubuntu 16.04 LTS?

[Alan Lord]

I'm not getting very far trying to install 7.0.1 on the above server.

I get through all the initial screens of the installation process until 
the very final one (where you choose Accounting as your type of 
business) and then the install procedure dies.

In the javascript console the response to the final get request is:

> <br />
> <b>Fatal error</b>:  Uncaught Error: Call to a member function Execute() on null in /var/www/html/vtiger7/include/database/PearDatabase.php:357

> #7 {main}

If I pre-enable the debug log in the log it is full of:

I have installed a customer's older vtiger v6 system on here already and 
this is working on the same server so I must have the right 
php/apache/mysql modules in-place or that one wouldn't work surely.

In the config.template.php I tried forcing the _DB_TYPE_ var to mysqli 
but this didn't make any difference.

I attach a copy of the pre-requisites screen. (I have some error logging 
to try and trap what is causing the issue)

Anyone got any ideas?

Cheers
