Prestashop install error - Configure shop information - prestashop

Question

I'm installing prestashop 1.6.1.10 on ubuntu/xenial64 (vagrant).
I get error on Configure shop information - An error occurred during installation...
In the log I see:
[Tue Feb 14 08:27:12.364749 2017] [:error] [pid 7587] [client 55.55.56.1:49446] PHP Fatal error: Uncaught PrestaShopException: Property Currency->decimals is not valid in /vagrant/prestashop/classes/ObjectModel.php:909
Stack trace:

#7 {main}
thrown in /vagrant/prestashop/classes/ObjectModel.php on line 909, referer: http://dev.imagine-lotus.design/install/index.php?restart=true
What can it be?
I've installed this same code, on the same ubuntu image before and it was OK.
EDIT:
I by-pass this issue by commenting out /classes/ObjectModel.php:909
I will un comment it after install is done
NOTE: after install an error in the front, I had to create a currency in the backend to solve it
I'm still getting errors, I noticed that prestashop was installed with multi-language, which is different than previous installation.
In the install process I didn't choose to install other language than EN,
Maybe chrome passes some variable that presta recognize as my native language and tries to install, and fails

so I Use Firefox instead of chrome and solve the problem

I got the same error while installing Prestashop 1.7 on licalhost xampp. But in my case, I did not even get the error log to find out the error, moreover, the installation request was being made via AJAX so error identification was tough, but after more research, I found out the source of the error.
C:\xampp\htdocs\prestashop\classes\localizationPack.php
I used
"try" and "catch"
to identify the error. The error is originating from
C:\xampp\htdocs\prestashop\vendor\icanboogie\cldr\lib\webProvider.php
as a result of network problem. Here, the script needs to send a cURL request to an online location, so if there is no internet connection, it shows that error.
After finding this out, I connected to a connection and tried it again and it worked perfectly.
Try that too.
Hope it works as it did for me.
