Hi,
I am trying to reinstall elasticsearch & Kibana in my Ubuntu 20.04 OS. There was some issue with Kibana loading, I tried fixing the yml files of both of them but port 5601 kept showing Kibana server is not ready yet.
So, I uninstalled both kibana and elasticsearch, removed /var/lib/elasticsearch
, /etc/elasticsearch
, /var/lib/kibana
& /etc/kibana
folders and started afresh.
But now when I run sudo apt-get update && sudo apt-get install elasticsearch
, I get below error:
Err:23 http://ppa.launchpad.net/cooperjona/nitrotasks/ubuntu focal Release
404 Not Found [IP: 91.189.95.85 80]
Err:24 http://ppa.launchpad.net/webupd8team/java/ubuntu focal Release

Reading package lists... Done
