I tried to start Kibana 6.5.0, yet got following error:

and what really weird is, I have 2 Kibana VMs and the other Kibana started without any issues, yet this one isn't... and they're exactly identical...

Please advise.

I think it's the same issue :

I resolved it by commenting out the following settings in the kibana .yml file:

#xpack.security.enabled: false
#xpack.graph.enabled: false
#xpack.reporting.enabled: false

5

I already have disabled Graph and Reporting (prior to 6.4.2), however I can't disable Security.

It's an issue that we'll fix soon, please follow https://github.com/elastic/kibana/issues/25728 to know when this is fixed.

For now you either need to enable reporting or disable canvas (Error: Module not found error on 6.5.0 upgrade).

Best,
Oleg

I confirmed, the real "workaround" (at least for now) is:

xpack.reporting.enabled: false

8

Hey,
@alexus I tried the workaround, but it doesn't work.
How is this issue going on ?
Will it be released soon ?

9

Hey @sialagio,

The workaround is to enable reporting, not disable (i.e. xpack.reporting.enabled: true).

Best,
Oleg
