Kibana failed while upgrading

[Vladpov]

Hi guys,

I started an update and upgrade commands on my Ubuntu machine with Elastic Stack and it upgraded Elasticsearch and Logstash succesfully but it failed while updating Kibana and asked me some question if I wnad to follow default option or so and I agreed.

Now when I want to access Kibana it says "Kibana server is not ready yet" and elasticsearch failed to start with following message:

root@bak2:~# systemctl status elasticsearch.service

How can I get back or upgrade Kibana to 7.4 version. I was using 7.3

Hey @Vladpov

i had the same issue this week and after i enabled the kibana logs in kibana.yml, i was able to see that at startup it was trying to migrate the kibana version with the index ".kibana_task_manager_1" and ".kibana_task_manager_2" (not 100% sure about the name, already removed the logs) just enable logs and you should see it as error.

after i removed the indices and restarted, then it was working again.

Cheers
