Grafana.ini do not open Raspberry Pi 3

Hi,
i need to configure Grafana.ini but unfortunately my Raspberry tells me that “do not open” Can you please advise me how to open this file? Thank you.

I had this problem yesterday when I installed Grafana on a Pi 3+ using the apt-get installation method described on this page. http://docs.grafana.org/installation/debian/

My solution was to completely remove Grafana using sudo apt-get remove grafana --purge

Then I used the method shown on this page https://grafana.com/grafana/download?platform=arm and installed the ARMV7 version. I have had no further problems.

Unfortunately this did not work, the file can not be opened.
But thanks-

Does this file exist? Which rights? Which user you are trying to access this file?
