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

[efficks]

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.

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• Grafana Image Renderer version: 2.0.0
• Grafana version: 7.1.1 (3039f9c3bd)
• Installed plugin or remote renderer service: None
• OS Grafana Image Renderer is installed on: Ubuntu 20.04 LTS
• User OS & Browser: Windows 10 & Google Chrome
• Others:

I had the same error, but (in my case) this was not a bug, but a missing dependency (as mentioned in https://grafana.com/docs/grafana/latest/administration/image_rendering/#troubleshoot-image-rendering).
Could you please check, if all the required libs are in place?
ldd /var/lib/grafana/plugins/grafana-image-renderer/chrome-linux/chrome

[jagaboom]

I've also been battling with the same issue.
I managed a work-around for my particular requirement which was a Dynamic-Text_Renderer, but it was a fudge so I'm still trying to get to the bottom of this error:

Failed to get browser version" logger=plugins.backend pluginId=grafana-image-renderer err=map 

Seems like it's quite a common fault, and a possible solution for you may be found here (although it didn't fix things for me):

[andreas-noethen]

ldd /var/lib/grafana/plugins/grafana-image-renderer/chrome-linux/chrome

libX11-xcb.so.1 => not found
libXss.so.1 => not found
libasound.so.2 => not found

please check if those dependencies are really needed... screensaver? sound architecture?

[mgergye]

@andreas-noethen you're issuing the ldd command literally against the chrome binary - those shared libraries are required by google chrome, not by grafana and/or grafana-image-renderer...

[SincerelyUnique]

+1 same issue
I have installed the plugin by grafana-cli and execute ldd /var/lib/grafana/plugins/grafana-image-renderer/chrome-linux/chrome, and restart, but when I open the grafana page and try to add a notification channel(choose Include image), it still display:

No image renderer available/installed
Grafana cannot find an image renderer to capture an image for the notification. Please make sure the Grafana Image Renderer plugin is installed.

Please contact your Grafana administrator to install the plugin.

[lazycoder-ru]

Same. The plugin was installed through cli tool, but Grafana logs that plugin is not installed.
The command "grafana-cli plugins ls" says that plugin is installed. No error messages in Grafana logs.

[dave-z34]

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

[marefr]

Running Ubuntu 20.04.1 LTS and have no problem. I had Chrome installed though.

[EDIT: It is broken again. Ugh.]
OK. Thanks for the ideas. This is what worked for me:

• Install the actual Chrome by using these instructions: https://itsfoss.com/install-chrome-ubuntu/#install-chrome-terminal
• (You may need to install libgbm1 & xdg-utils first as they are depenecies)
• Install the renderer (grafana-cli plugins install grafana-image-renderer)
• Restart grafana-server
• Error gone

[k4r1mun]

I still cannot make the renderer to run even though i installed all the libraries. The plugin seems to be registered but the service is not running from port 8081. Is there any way to start the service? I tried restart grafana but no change.

[AgnesToulet]

@k4r1mun Hi! There are two ways of running the image renderer: plugin mode (run as a plugin by the Grafana process itself) and remote mode (run as a web server that you need to manage).

To run it in plugin mode, you need to have the plugin installed (that seems to be the case) and the rendering section in your configuration file empty:

[rendering]
# Options to configure a remote HTTP image rendering service, e.g. using https://github.com/grafana/grafana-image-renderer.
# URL to a remote HTTP image renderer service, e.g. http://localhost:8081/render, will enable Grafana to render panels and dashboards to PNG-images using HTTP requests to an external service.
server_url = 
# If the remote HTTP image renderer service runs on a different server than the Grafana server you may have to configure this to a URL where Grafana is reachable, e.g. http://grafana.domain/.
callback_url = 

[k4r1mun]

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