The log does tell you exactly why it’s not starting - crit (critical) message saying that it cannot parse your grafana.ini

So check and fix the error in that file (around where it says “anonymous, data proxy will add”).

“/etc/grafana/grafana.ini”

thank you!

i changed anonymus= true

but what i have to do with data-proxy?

thank you!

i changed anonymus= true

I trust that you spelled it “anonymous”?

but what i have to do with data-proxy?

Now that you have made those changes, what remaining errors do you get when
you start Grafana?

Antony.

heheee, yep anonymous is true :wink:

no proxy in my network! Are the ini with the default “data proxy” settings ok?

thank you

You have a newline in your .ini file that should not be there. Lines starting with a # or ‘;’ are treated as comments and are ignored, so the lines should look like this:

# If enabled and user is not anonymous, data proxy will add X-Grafana-User header with username into the req$
;send_user_header = true

But you have a newline part way through the comment so it is invalid, like this:

# If enabled and user is not 
anonymous, data proxy will add X-Grafana-User header with username into the req$
;send_user_header = true

Remove the newline so the comment is back on one single line starting with ‘#’

hey guys thank you.

the problem was an old grafana installation and under /etc/grafana/ a lot of files was not deleted like grafana.ini … after deinstallation.

sudo apt-get --purge remove grafana
sudo apt-get remove --auto-remove grafana

so the old ini file was there but not the new one after installation.

thank you guys so much
