You're saying that you've installed chromium. I've used google-chrome-stable from the documented repos here: https://github.com/Icinga/icingaweb2-module-pdfexport/blob/master/doc/02-Installation.md

Run something like this to verify that you've got the latest supported version of Chrome:

[root@icinga2-elastic ~]# /bin/google-chrome-stable --version
Google Chrome 73.0.3683.103

[lokidaibel]

Jep. Installing latest chrome instead of chromium did the work.
Please adjust the dokumentation cause this is missleading.

[dnsmichi]

Please adjust the dokumentation cause this is missleading.

Which docs version are you referring to? I have adjusted the docs yesterday afternoon.

[lokidaibel]

I mean the: "The module needs Google Chrome or Chromium supporting headless mode."
in the Installation.md.

Sounds like it could would worke also with chromium. Atleast at my installation it doesnt. @dnsmichi

[dnsmichi]

I didn't write the initial docs, I'll ask Eric next week about it.

Hi,
i had the same problem under Debian 9.
I'd added 2 symbolic links:
ln -s /usr/bin/google-chrome-stable /bin/google-chrome-stable
ln -s /usr/bin/google-chrome /bin/google-chrome-stable

Now it works
