I am running elk on debian.
Today there was an update installed, which bumped the logstash version to 6.8.16 from 6.8.15
After this logstash fails to start.
I see the following in the logs:
```auto

```
Does anyone have ideas on what I could do

Does anyone know, if the whois plugin was part of the default bundled plugins?

The `whois` filter is not part of the bundled plugins, it is a third party plugin, you will need to install it again every time you upgrade.
