First run wizard problem

Hi, I whish to connect my client to a running nextcloud server. I am running ubuntu 16.04 in my pc; so I did:
sudo add-apt-repository ppa:nextcloud-devs/client
sudo apt-get update
sudo apt-get install nextcloud-client
after successfull installation (with required packages) I run nextcloud and the wizard appeared; then I specified the server address but at next screen I see quite a blank screen in which is impossible to specify values.
Anybody has experienced this behaviour and how to get rid of? Or there is a workaround to manually write required values in config file avoiding the wizard?
Thank you

Please check the logfiles on your server. There is hopefully an error or something that explains why you see a white page.

I did another installation following tutorial and now is ok.
Thank you
