grafana-image-render not working in Ubuntu 20.04 and Grafana v7.1.1 (3039f9c3bd)

What happened: I’ve install Grafana v7.1.1 (3039f9c3bd) on Ubuntu 20.04 LTS. I installed grafana-image-renderer with the grafana-cli command grafana-cli plugins install grafana-image-renderer

Restart grafana

In the Grafana plugin list, the plugin is registered but marked as unsigned. In the share panel, this message still appear To render a panel image, you must install the Grafana Image Renderer plugin. Please contact your Grafana administrator to install the plugin. What you expected to happen: Be able to render a graph to png through the share panel.

I was able to fix this issue by looking at the grafana.log and installing the following packages as follows:

sudo apt-get install libxcomposite1 libnss3 libatk-bridge2.0-0 libgtk-3-0

Hi @AgnesToulet , it works! Previously I uncommented the server url but not the callback url. Thank you for the help!
